I know it's pre-order and shipping in March 2013.
Anybody know how much it would cost? seeing as it includes a hand controller I expect it will be $200 plus.
Still, not a bad price.
If in the future they add autoguiding... that would be a killer feature.

still decent-ish. a bit more than i expected, i don't see CG5 ASGT buyers getting this.. but for the bigger mounts (like my CGEM) probably still ok.

My problem is it is just an alignment aid- it won't guide, so it's one more doohickey attached to the mount.

The problem with using the StarSense for guiding is that it's a wide field device, with a 50mm F/2 lens. That will mean that the pixel size is probably too big to give accurate guiding.
But who knows! Maybe there's a software solution that will give sub-pixel accuracy. Or put a focal length extender on the front of the lens.
Another option would be a Polar align helper. With knowledge of the mount it would be possible to provide information such as how far to turn each screw.
I must stress I've no inside information though. This is just speculation.
Chris.

my thought was to use the StarSense to align on many stars.
after that's done do a usual ASPA. rinse and repeat.
didn't realize its a 50mm lens though. the SBIG efinder is a 100mm lens.. so might still be workable if Celestron ever adds guiding functionality.

I for one can't wait for this, too bad winter will almost be over by the time it comes out. Especially when it's -20c it would be nice to just turn on the scope come back in 3 minutes set it to a target and begin imaging. Also many times I've thought I was looking at one star when infact it was another and had to restart alignment all over again.

According to celestron it is a 20mm F2. Not very suitable for guiding though I have used a 50mm F3.5 finder as guidescope.

My question is if the brains are in the new controller could one use a usb camera with a longer FL lense? I guess the initial polar alignment would have to be closer with a more narrow FOV but perhaps a guidescope could be used or a modified finderscope.

It's suppose to do point modeling too..

The mount modeling is probably based on the internal nexstar modeling since it can do up to 6 alignment stars. 5 more than the AP!

From the press release it says,
"StarSense replaces expensive software used for Advanced Mount Modeling, providing superior pointing accuracy from horizon to horizon. Users can add as many calibration stars as desired to give their telescope mount a new level of accuracy."
So - that is more than 6 stars and must be different, and there is a different handcontroller.
They don't say what it does regarding polar alignment - at least I didn't see anything.

From the bits i've read and pics i've seen from the Celestron website and bits i've gleaned from facebook etc, it seems the HC that comes with it is an HC+ handset which has the auto align functions plus all the other usual bits including ASPA. I shall try to find again and put some links up
Edit heres one
Celestron Starsense
If you look at the HC pic its the same as the HC+ except it has Starsense printed on it

Very interested in this technology...will make setup much quicker...no more 2 +4 star alignments.
Wonder what the procedure will be after letting this thing do its thing and then doing a ASPA and manually adjusting the mount....guess just let it align itself again to take into account the mount being moved in alt/az...?

It'll probably take a little longer, but at least you can be unloading the car or something while it does the 2 + 4 unattended.
Shouldn't be necessary to realign; the mount knows what you've done. I never needed to realign my CGE after ASPA.

From what I've seen looking at a SkyProdigy HC the display is different, it seems to have a four line display, the lowest line has help information.
There's a SP manual on the Celestron site, I doubt the StarSense manual will be put there until after it's released.
We can only speculate about what the SS will do, especially with an equatorial mount, because so far the SP has been alt az only. There's all sorts of possibilities - polar align helper where the scope tells you how far to move each axis - multiple align stars - auto precise goto where the scope moves, has a look to see how it's doing and then does a final update. Possibly guiding although that may be more challenging.
I guess that the first version will not have everything but that additional features will be added later.

Probably not. Alignments have grown ever more automatic for alt/az mounts and this one goes a long way (appears to be a more effective implementation than Meade's LS series). An EQ mount does require a reasonable accurate initial polar alignment, though, before any star alignment can be effective. Automating that would be a far more complicated (and expensive) project.

Chris, and JRCrilly - I don't quite get it. I can see how Starsense will help out for an AltAz'muth mount - but for a GEM? Are we assuming you don't bother with an initial polar alignment, and just let Starsense do its thing first (with poor polar alignment) - and then how does the mount maintain tracking thereafter? Without reasonable polar alignment, both the RA and Dec need constant driving to maintain tracking...? Or maybe as other said above, ASPA is still required thereafter...? Fox

Yes, it can automate the star alignment, but as I mention above the polar alignment will remain a manual process.

So you hit enter ...wait 3 minutes whilst starsense aligns the CGE PRO, for example, mount really accurately......then do a normal aspa routine if you need to.

Does this assume all stars are available for alignment? I would guess there are many folks who have blocked views of certain sections of the sky.
Or can you pick what stars it can align on based on user input?

It can be allowed to pick its own regions of sky or you can manually point it to different locations that are unobstructed.
Got that from looking at SkyProdigy manual on Celestrons website

I got on the pre-order list yesterday, sounds like it will make my setup a little easier.
I wouldn't be surprised if someone eventually made a Eq. mount with motors in it to make small adjustments to polar alignment. Doesn't seem like it would be terribly hard to do.

Maybe I'm missing something here but isn't it a necessity that the FOV of the Star Sense be centered on the same FOV as your scope? If you are setting up your system from scratch every time, wouldn't aligning the two take just as much time as just using a Telrad and a reticle? After the frustration I had the other night getting my scope aligned I'm dying for something like Star Sense, but it has to be easy to set up every time.

I don't want to hijack this thread but my frustration was that I set up my scope in the dark and I didn't get the Telrad's dovetails inserted into the holder correctly. To answer my own question, I just read the March Sky and Telesope. There is a Celestron scope review in which the author says Starsense is good enough to get an object in the eyepiece, but not centered. You then go to a calibration page in the menu to get things centered up.

Not to be insensitive, but it sounds like you're looking for technology to compensate for user error. StarSense may indeed be great, but only it it's set up right, which is probably fraught with its own complications. Please take a little more time to see if you really need it. Set up your rig correctly and try again. After all... "Courage is being scared to death, but saddling up anyway." If you stay with it you will probably learn to put everything together by feel; until then, set up in the day or use a red flashlight.

If you refer to the accuracy of the alignment, the camera's focal length doesn't enter into it. Nothing about the image is measured in any way; only the relative star locations are used to match up a piece of sky. The accuracy will depend only on the accuracy of the star locations in the database used to plate solve the images, and the algorithms used.

The answer, I think, is not the Celestron gadget, but tuning up your setup procedure. That's a lot cheaper, too.

Calibrate – Your telescope’s camera may need to be calibrated if the telescope cannot find objects after being successfully aligned. To Calibrate the camera: 1. Slew the telescope to the bright star that you are trying to find. 2. Select Calibrate from the StarSense menu option. 3. The hand control will display the current pixel position of the center of the camera sensor. 4. Use the direction buttons to manually center the bright star in the eyepiece. Press ENTER. SkyProdigy will then take an image of the sky and calibrate the center of the camera sensor with the star seen in the eyepiece.

I have one on pre-order too. All I can and will ask of it is to be able to put things as close to center of the eyepiece as is reasonable. For outreach I want to use either sky safari with the skyfi wireless adapter or SkyQ from Celestron. I want to tell it to go to an object while I discuss with those around what it is they can expect to see. I want it to be in the eyepiece once it gets there. Or even better, using something like the Mallincam to show the view on a projector screen. I don't have to say..hmm ok hold on a sec while I find it in the finder and center it. So if the StarSense can do that for me...

You know what would be cool? A similar product but generic to all mounts, one that would for example plate solve on PC (without the purchase of extra software) and do pointing corrections through ASCOM driver of your mount. I'm thinking a sleek simple to use, integrated solution

I have one on pre order as well. I believe there is alot of room for advancement with this product. Lets see if Celestron takes advantage of it.

I think others or maybe myself are thinking of this accessory in the wrong way.
I see its usefulness out of the box being:
Level tripod
Attach mount (alt/az for me)
Power on and let starsense do initial star alignment while I continue setting up
Then do a quick calibration between starsense and ota.
Then enjoy
For a Eq you will have to add all star polar alingment after callibrating starsense to ota to get a better polar alingement.
This would, to me, elliminate the need for a finder scope during the alingment process.
Also as mentioned before the starsense makes a map of the stars and the calibration tells the mount where the ota is pointing on that map. So the two don't have to be actually aligned like a finder scope does.

I am thinking tat the camera to ota calibration should be done before aligning with Starsense.....
Or have i missed something?

I'll get back to you on that in a month or two. I have a CPC 1100 and a CGEM DX 11 Edge. I'll be trying it on both.

I honestly don't know the order of operations or if it will work the way I described. I was just speculating from what I read about how it works with the sky prodigy. Although that already has the camera mounted in relation to the OTA saddle so maybe you do have to do that first.
I'll be posting about mine also when it arrives, but can only test with my 8SE maybe a club member will have a eq. mount to test it out on.

My guess is that out of the box SS will align on the centre of it's field of view. There's an option to compensate for this and this is an electronic/computer way of aligning a finder. You do it once and as long as you always replace your finder/SS module the same way you don't need to do it again.

There is a Q&A page on Celestron's web site. Link for it below. Here is an excerpt on polar align and use as a guide cam:
Stephan G. asks, “Can the StarSense Accessory help polar alignment in some way?”
-StarSense won’t directly assist in polar alignment. However, because the GoTo alignment is very accurate with StarSense, All Star Polar Alignment becomes more accurate. You’ll be more closely polar aligned after just one iteration of the All Star alignment procedure. (This answer applies EQ mounts and CPC + Wedge mounts only.)
James D. asks, “My question is, can StarSense be used as a guide scope for imaging?”
-Not currently – the main reason is the 20mm f/2 lens used in the camera does not have enough focal length to accurately guide longer focal length telescopes. We acknowledge this feedback!
William W. asks, “Will the new StarSense Accessory guide me through a polar align on my CGEM DX? Does it replace my hand control?”
-StarSense replaces the existing NexStar hand controller. It does not assist polar alignment. It automatically aligns the GoTo. Here is the link to the full (short Q&A): http://www.celestron.com/portal/articles/cat/howto/post/ask-team-celestron-st...
This is of some interest to me because per Celestron they are able to align it decently in their Gardena industrial park with all the associated sky glow, LP, and direct light interference and since many of the outreach events I go to tend to be in bright places like outdoor mall's and "old town" city streets so this would be a great step up from the bump and shuffle I do now manually tracking things. It would really nark off the dobbies if I roll up with an auto track SCT!

Hilmi,
I've been thinking exactly the same thing. And if it did auto guiding as well, that would be the cat's pajamas. However, given the state of mobile processors, it would seem this should be able to go wheels-up and communicate via Bluetooth to a tablet or iPod sized device.

Well lets be clear. The GPS module was never "needed". All you have to do is peek at your smart phone, grab the coordinates and enter them manually. Takes what? 30 seconds? Not only that but I believe major cities are all there in the memory. All you'd have to do is pick the closest one and that should be good enough for Starsense to accurately pick the correct stars to navigate by.

There already is. It's called Astrotortilla and its shareware. All you need is a camera.

I agree AstroTortilla is pretty neat.
It interfaces with APT, Nebulosity, MaximDL, and PHD for capturing images to solve, and allows you to specify an image file taken by another application.
You need to have a lot of disk space however. It uses the astrometry.net plate-solving engine which was written to run under Unix. astrometry.net uses some very large data files to support its blind solving capability. Also, if you are running the Windows operating system you need to install cygwin which provides a Unix-like environment for astrometry.net.
I used it successfully, for the first time, at the Winter Star Party. I am now a fan!

Cheers Rick. One tip is that once you figure out the file for your given telescope aperture you can remove the other ones. It will cut down on the time it takes to solve as well as the HD space.

Did he calibrate the camera with the scope?
This has to be done so the center of the cameras sensor is collimated with the center of the fov.

I agree with Howard that the mount in the vid has to be calibrated slighty. If whatever object is in the FOV then the calibration would be very simple.
Also it seemed like it he just got it and didn't know that much about telescopes, because walking around with the camera's light on while the scope is trying to scan the sky making its job that much more difficult.
So to put Jupiter in the FOV I think is a win for the mount, and it just needs a slight calibration to put future objects in the center.

Now it's changed to July!!
Another product I know was slated to come out in early 2012.. it's now 2013.. (the site still says available in 2012) come on manufactures.. the suspense is maddening!!
What will be interesting is if the star sense aligns on the refracted pole and if the point model takes atmospheric refraction into account for the object when the object is in different parts of the sky..
Uh.. look ma.. no wires!

fyi I put an older 130SLT OTA (650mm f/5) on my new sky prodigy mount, and after aligning the StarSense with the scope's OTA, I'm very impressed - with a 6.7mm ES 82° eyepiece (97x, 0.85° TFOV - along with 11mm eyepiece as well), it would put most all the messier galaxies in the Leo/Virgo region within the eyepiece's FOV (a handfull were a little too dim for my location). Slewed it 180° around to the open clusters in Auriga and they are still almost spot on. fwiw there's a note in the manual that even if you just collimate your optics (eg, in a Newt), you are advised to perform the alignment again.

FWIW...I also purchased the skyprodigy mount with a 70mm refractor that I discarded--just so I could have this technology for my 6se SCT ($229 at B&H on closeout). I realize that the 6se is too heavy (mount says 8lb limit), but it seems to work fine. Just had to cut off some of the cowling on the mount to accomodate the larger radius of the 6se.
The Star Sense tech really does seem to work. It takes three pictures and then solves the sky. After that, gotos are really quite good (about a 3 minute automated process). StarSense does NOT track, however--at least not in the skyprodigy incarnation.
My viewing site is completely obstructed to the north because of a large tree, mostly obstructed to the SW due to my house and tress all around otherwise. But I have found a starting position that allows the system to calibrate reliably.
The mount is a little flimsy and it takes several seconds to stabilize with the 6se on it. But this tech on another mount would be just perfect.
I recognize that many don't see the need for this tech--but I have found that it further decreases the energy barrier to getting out and observing. It takes 3 min to start slewing to objects--and if clouds roll in, I don't feel like I have wasted my evening. If I see a break in the clouds, I can take advantage of it--even if rain is coming in half an hour--pretty cool.

Make sure tracking is no Disabled in the menu (you can select Sidereal, Lunar, Solar, or Disabled). The mount will track once aligned.
You're spot on with your conclusion, the scope just makes the decision to bring out the scope so much easier (yes, regular SLT/SE/CPC/etc. alignment for a quick look should only take but a couple of minutes) - just the other day when I was back late evening from an observing session on the outskirts of town, I don't think I was done yet with observing, but wasn't up to pulling out the gear from the car to setup all over again - I took a couple of minutes to bring the SkyProdigy from inside the house to the backyard and fired it up; in the meantime I unloaded the other astro gear from the car into storage. 15min later when my other stuff is put away, I stepped into my backyard and the SkyProdigy was there waiting for me to get my last fix for the night (granted, sky conditions was bad compared to where I just came from).

Sucks this is delayed. One thing this product would really help is people who rarely make it to dark skies. When I align in a dark sky I have a hard time telling which star is which everywhere you look there are stars. At home there are a very limited number of visible stars and in some ways this makes it a lot easier to align.

I know a guy who occasionally comes to club sessions, who is beta testing Star Sense for Celestron. He was there last Saturday. I didn't get a look at it in action, but did briefly chat with him as he was packing up. It sounded pretty cool, really. True democratization of technology which should open the GOTO GEM door folks intimidated by the prospects of self-alignment of a GOTO mount.
The only question is this - $300+ is a lot of incentive for the intimidated to conquer their fears rather than plunking down for the technology. GOTO mount alignment, at least for visual use, is not that difficult really and, especially with help the first time from someone who has done it before, can be mastered literally in a single session. What price convenience? I'm thinking $150 rather than $300 would be attractive to those who have no fear of self-alignment, but are lazy. I'd pay $150, but not $300, just for the convenience factor. Now if it also autoguided...

Jim

I agree 100%!!! If I try to align the scope well after the sun sets I sometimes have a lot of difficulty because every star in the FOV looks the same. It can be very difficult for me to center on the correct one. Just after sunset it's not a problem because only the brightest stars are visible.
I ordered this and can't wait for it to arrive... And compared to many items for sale for this hobby I think it is very reasonably priced.

Crossing my fingers that the delay is due to many people wanting to also use it as a autoguider and Celestron may have a solution to do so.
Guess I'll be waiting to see what happens in July.

After that, gotos are really quite good (about a 3 minute automated process). StarSense does NOT track, however--at least not in the skyprodigy incarnation. ... I recognize that many don't see the need for this tech--but I have found that it further decreases the energy barrier to getting out and observing. It takes 3 min to start slewing to objects--and if clouds roll in, I don't feel like I have
Make sure tracking is no Disabled in the menu (you can select Sidereal, Lunar, Solar, or Disabled). The mount will track once aligned.
You're spot on with your conclusion, the scope just makes the decision to bring out the scope so much easier (yes, regular SLT/SE/CPC/etc. alignment for a quick look should only take but a couple of minutes) - just the other day when I was back late evening from an observing session on the outskirts of town, I don't think I was done yet with observing, but wasn't up to pulling out the gear from the car to setup all over again - I took a couple of minutes to bring the SkyProdigy from inside the house to the backyard and fired it up; in the meantime I unloaded the other astro gear from the car into storage. 15min later when my other stuff is put away, I stepped into my backyard and the SkyProdigy was there waiting for me to get my last fix for the night (granted, sky conditions was bad compared to where I just came from).
My apologies--the Sky Prodigy DOES track (quite well). It does NOT autoguide. Sorry for the confusion!!

Hopefully not! I am planning on buying two if StarSense gets good CN feedback. I have a CGEM DX and a 8SE and being able to set both up, fire up StarSense and walk back a few minutes later to two aligned mounts is awesome. If this works out, it could motivate me to pick up a VX mount also.
Pricey yes, but this is my hobby and if it works as reported then I will opt in.

I'm way more interested in the pointing model feature than the alignment feature.
How does the pointing model feature differ from the alignment feature?
2+4 is kinda a pointing model. A pointing model keeps track of where stars and objects are in the sky. Bisque pointing model takes flex, refraction, etc into consideration. I hope the star sense does too.
It would be more like a 200+ star calibration.

I think we need to manage expectations a little here.
AIUI the StarSense/SkyProdigy gets three positions by pointing in three directions, acquiring an image and plate solving it. That give three positions as Ra and Dec and the rotation of the image. It will give a good alignment with corrections for the major mount errors such as Ra and Dec offset, polar align error and cone error.
Corrections that can be calculated, such as refraction and precession can be allowed for.
But it's not a 200 star pointing model, there's no way that 3 positions can be turned into 200.

The price of gadgets aside, you have to admit that this is a great time for amateur astronomy. If Meade's LX-850 works, you can bet that Celestron will begin to offer something similar at the 2014 NEAF that will autoguide.

Now, that would be really cool. My biggest complaint about it is that I want something that would plate solve for me. I can align my mount just fine; I need better accuracy.

Plate solving is taking a picture of a star field and computing the position of the picture in RA/DEC by comparing the position of the stars in the picture to a known catalog.
Typically you need to have some location and scale information that gets you relatively close to the actual location. But there are systems that also do the matching blind.

I don't know the technical details of the StarSense but just received one of the SkyProdigy mounts. I read everything I could find on the mount before buying (got a great deal from Adorama, $229 new) and found the following post:
Quote:
The SkyProdigy telescopes are toys with autoguiding piggybacked onto them. They're the same kind of telescopes you'd find at Costco or WalMart.
The LSs are serious SCs. There's really no comparison.

>UNQUOTE
Nothing could be further from fact, WRT Sky Prodigy. Cloudy Nights prides itself on objectivity - before you categorically snob a telescope, please consider owning or at least operating one for a spell to give it a fair shake. The staff here obtained two early on, to study the guide algorithm. Stand by for long-winded response <wink>....
Been an ATM/AA for about 44 years, scratch-built optics, mounts, gotos and robotic scopes and their electronics and systems. Bought the same, too. Eventually became a professional astronomer and observatory director in that time. I say that because, I have not only been involved with buying, making and operating goto and upper end avocational telescopes for many years, I am quite familiar with the astrometric methods used in a Sky Prodigy that we use in large professional instrumentation in the $ten-figure class. So I think I can speak with some accuracy on how the little Prodigy's work.
Contrary to the innuendo, this kind of sky alignment algorithm is not used in dimestore telescopes, but is a technique used in the orientation and navigation of billion dollar spaceborne intelligence systems, strategic aircraft, and special shipboard systems. That "ACN and ST" (Automated celnav & star-tracker) field is far, far more advanced than anything seen here on CN; and while the little Sky Prodigy is not so fancy either, its pointing heritage certainly does not put it anywhere near "dimestore" class. Having used one at length, I can say it does not deserve that slight.
While Sky Prodigy certainly is aimed at novices, that alone is important to an amateur astronomer -- most of whom want to perpetuate the hobby. I get countless PR appeals from newbies that they cannot align the telescope to then "goto", and along those lines, I am sure Celestron wanted to answer that key issue for novices. You can't maintain an avocation's people-base by intimidating entrants. But Sky Prodigy still is useful for more than just the rote beginner as we see it (and no we were not paid by Celestron LOL).
When my staff got ours a year ago to actually see how Celestron's code aligned the instrument the turned out surprisingly easy for us to use (our pro's know the night sky BTW) and reinvigorated an aesthetic appreciation for the sky. Like I said, we were comparing SP to advanced alignment systems -- specifically to understand the relationship of the StarSense algorithm to angles-only Kalman filtered algorithms . There even, Celestron did a quite good job -- especially for the price. We may look at "Autoalign" on Meades next, but they are really not in the same alignment league, relying on GPS, time of day, expected positions, etc, not star fields alone. Last year's news, Meade and Celestron (with somewhat similar SkyAlign, have tested those), can go arm-wrestle about who is on who's turf there; we wanted to focus on how the SP did its alignment.
We've tested a Sky Prodigy for a year... and it is no dimestore telescope. While optomechanically similar to its Nexstar brethren, and at least equal to that line of optics, the mount at or better than an SLT's beefiness, and it is much much easier to operate. Every time I could walk up and goto 30 objects in sequence across 2 pi-steradians -- and find them well centered, after every starsense alignment. I know the night sky well, but it sure is impressive to set the unit out, and go inside for a coffee, come out and watch it finish self location, then present itself for tracking. The 130 would be easy to backpack as well; did that. Optical collimation remains quite solid both using ole Techtron tools, and also cross checking in our optics lab on a Zygo interferometer-- after a year being roughly used.
BTW people here have hip-shot that the instrument is basically a" Nexstar with autoguiding piggybacked onto them". This is also false and very misleading; sounds like someone got confused with Meade's Starlock system.... Go read up on how the Sky Prodigy operates (and some nice videos and Youtubes out there too). I don't believe it's the best principle instrument for an advanced amateur... any more than I would put an advanced amateur on a robotic liquid helium cooled IR 2-meter with an echelle at the naysmith, a professional's tool... BUT, SP would be a great, quality beginner telescope to bridge a lack of sky knowledge and get an exhuberant youngster excited to keep looking at he sky. It's a great knockabout quickie scope too, can throw in the car or the pack (sort of) for some desert fun.
In fact it would come from a line more capable, and is IMO better than than the LS. And as an aside, I'd be careful about how one uses the term "serious SC" as amongst amateur telescopes, as _very few_ currently marketed SC's are indeed "serious" telescopes, from an expert point of view, either - Point being -- it's *all* a *point of view* - and such subjectivity should be avoided when fairly evaluating an instrument... SP is as optomechanically decent as most all other small Celestrons.
Finally, I know some AA's disdain making alignment and learning the sky 'too easy', as abjuring some rite of passage. To them I'd say don't dismiss this novel and simpler method for aligning a telescope, as some short circuit as to learning the sky, anymore than oldsters of yesteryear used to dismiss a 4 function calulator as cheating vs. a slide rule... I've actually seen little kids at open houses marvel at the auto-alignment, then start to spatially grasp the sky as the SP marched from object to object. It is the future, and hopefully the method will spread into upper end amateur instrumentation, like GOTO once did.
So, the technology under the Sky Prodigy's hood is actually advanced, and not dimestore-trivial, and so instead makes the alignment, goto and operation all the simpler -- time to pay attention to other things more important. Like your smartphone made life simpler (allegedly LOL). If you are satisfied with Nexstar and CG quality, the Prodigy easily equals or betters that, but is just alot easier to use. If you like GOTO this is the next step. Try one; I will probably buy my own 6" variant in fact, after our staff experience with the littler SP's (I do wish Celestron sold just the Starsence mount, sans OTA; I have a nice 6" R-C that would be just great riding on a Sky Prodigy arm!). FWIW.... again sorry so long - I just did not want a dimestore innuendo have people miss what a different experience for our staff the little SP's provided. Your mileage may vary.
. link to complete thread Sounds like the technology involved does something distantly related to "plate solving". Just speculating....WC

With a wide field camera and a known focal length, which the Starsense has, I think doing a plate solve by matching up a hand full of stars in a given area of the sky isn't that difficult. We don't need to plate solve a thousand stars. Three or four brightest in its field of view would be acceptable I think. This is just speculation of course. The technology looks at th FoV and tries to center the brightest star at the position it "believes" it should find it. Then it centers on that star and marks/stores that coordinate. So why not process three stars in the FoV or five or ten? I guess it really doesn't matter too much. 2+4 is already pretty accurate. Having a device that does it automatically is really neat. That is all I ask for and all I require it to do. Anything else is just icing.

There was some discussion of how many stars the mount uses for alignment, in my light polluted (some skyglow, just outside of Branson, MO and neighbors yard lights) backyard using the manual alignment method (point at three unblocked areas of sky and let each area calculate) the hand control has been saying it finds anywhere from 30 to 100 usable stars. This is when visually I can see very few stars. Seems to work very well. Also, you can adjust it for the brightness of your sky...it can be overwhelmed if you go to a dark site but you just do the adj....This is using a tiny C90 mak scope....

Hi,
I'm glad someone finally came out with this technology. And I'm really glad it was Celestron. They were first aiming at children beginers with the sky prodigy telescope. I find it hard to believe kids have problems centering a star. Most kids can operate computers, video games, and smartphones, remote control toys better than most adults. At least better than I can. I think most problems people have was from putting the wrong time/date/location type information. But non the less its a good ideal to make it easier for beginners. I think the best benifit is for astrophotographers. This device will improve accuracy and assure goto's to DSO's are centered on our imaging chip. Many of them can't be seen until after you image.
Besides I really like gadgets and automated things. And I will enjoy watching the starsense align my mount. I think the price is a bit high but I'm willing to pay it. I like that it comes with a new handbox.
I only have one concern. Celestron can't you make the included handbox's cord longer. I find it frustrating that the cord is so short and theres no connector on the handset so you can't replace it with a longer cord. Or make it wireless, this is 2013 not 1985.

Well you can.
Celestron has the Nexremote software and the SkyQ link. Bot h of those work together to make it essentilly wireless. Also you can use an iDevice withe their skyq app. Or you can use Sky Safari and SkyFi module to be wireless. The skyfi module also allows you to connect with most popular software. For me I have a usb hub on my mount that I plug the celestron serial cable into and I control my mount via a long usb cable. So to recap, if I am standing right at the mount I pick up the hand controller and use it. If I am doing outreach or walking around at a distance away I use my iPad for wireless control of the mount and if I am doing imaging I am controlling it via a long USB cable so I can be somewhere warm. As for making a longer cable there is nothing special about the cables. Perhaps you can buy an extra hand controller and make your own longer cable for it. Maybe Scopestuff sells them already made. I haven't looked.

Hi,
Like I said it sure would be nice if the cable was a decent length. Its very short.
Those devices only make the computer connection wireless not the handbox. I have had a wireless handbox on my LX200R 10" for years. And on my TV, Vcr/DVD player Satalite box ect. I don't know of any modern device that still has a wired controller. But I would be happy with just a little longer cord.
Some time back I bought one of those extention cables and it fried my handbox. Now they say they test them but it would be nice if the one that comes with the mount was a little longer, or if Celestron offered an extension themselves. And I shouldnt have to modify a new handbox and make a longer wire just because they want to save 2 cents on wire. A foot or Two longer would do.
There are plenty of other people who complain about that wire being a little short too.

The SkyProdigy mount software currently doesn't allow for external computer control...this is supposed to change, I'm guessing they are waiting to release the Star Sense attachment and update the software at the same time. I just ordered an extension cable from a different company, they have them up to 25' long, hopefully no frying of my hand control will be involved... link

Well you talked about it being 2013 not 1985. I was just saying that Celestron has addressed the wireless aspect in a different way. Having a true wireless, perhaps bluetooth, hand controller with a charging cradle would be great. I have recommended that to both Meade and Celestron in the past.

Well, 2 mb isn't enough to get a catalog into it. It'd be cool if it was expandable via SD card or something.
It depends on the catalog. It holds the current 40,000 nexstar catalog database and the plate solve database with room to spare..
You are speaking very authoritatively about this Wolfman, do you have some sort of inside knowledge about the Sky Sense?

I had asked the following on TeamCelestron when the engineer said there was no need for latitude, longitude, ot time to be saved into the star sense HC.
"How would starsense know what/where the first alignment star should be without latitude, longitude, and time? Am I missing something? You must have included a lot of room in the HC for a complete database for plate solve without starting reference point.
Here is the reply:
How would StarSense know what/where the first alignment star should be...It doesn't really matter which star you go to first. You just take a (random) picture of the sky, and solve the plate. Now you have a a set of RA/Dec coordinates for those motor coordinates. Then you spin the motors a while and take another (random) picture. Now you a second set of RA/Dec coordinate to go with your new motor position. After you do that one more time, you have enough information to figure out where everything else in the sky is located relative to that. Before you start your alignment the HC asks you to put your mount in the "home" position so it won't crash into itself or waste time taking pictures of the ground. And if you have an EQ mount you will want to point the mount close enough to true north that you can do the polar alignment once the sky align is complete.
You must have included a lot of room in the HC for a complete database for plate solve without starting reference point. About 2 megabytes. Which is big for an embedded microcontroller. That database takes more space than the entire star catalog, the application code, and the text databases for all 6 languages combined. (NOTE: I am not sure if SSA will be multi-lingual like the NexStar+ hand control at its initial release).

I'm glad I found this thread, because this gadget (assuming it works as advertised) would be a godsend for me. As the years drag on, it becomes less and less pleasant to contort behind the finder in order to slew to and center the alignment stars--so unpleasant, in fact, that I only bother if I know I'll have time for an extended session.
But with StarSense, especially in the summer, I could just leave the scope in the garden, and then just pop out, start the gizmo, pop in for dinner, and then go out even for a short session. Five to ten minutes saved, plus achy neck and back--priceless.
And if Goto's deteriorate during the session as they so often do, it may be the difference between packing it up when faced with another manual calibration, or just hitting the StarSense button and admiring the sky while the scope gets itself ready again.
This is indeed the millenium!

Actually, I think that the Meade Lightswitch mounts were the first to do this.
I think that Lightswitch is an automated version of normal alignment, in which the orientation of the telescope (level, north) and the lat/long of the location is known, so the telescope decides which bright stars to align with and finds them - as a user would - and it does so by 'knowing' where they are in the sky and can point approximately to them blind, based on magnetic north, etc.
I think Sky Prodigy is also based on finding bright stars - but it doesn't need to know lat/long or north - it just finds 3 bright stars - any stars - and does an automated 1-2-3 align with them.
StarSense then takes it to two new levels by not needing centered, bright stars at all - but just patches of sky that have enough stars in them to plate solve with a medium sized database. This also means there is no time spent centering the star before recording its position. I also think that, from my early posting in this thread, it will include more elaborate mount modeling based on many stars.
This is just my summary based on what I have read and what makes sense to me. The two technical concerns are what happens when it can't plate solve for some reason, and how does it deal with slight misalignment of the camera with the scope. For the first I assume it knows when a solve fails so it just goes to another part of the sky in some semi-random way. For the second, I assume there is a calibration procedure done once, with a human, where you center a bright star to let it know the offset of the plate solve from the true OTA direction.
So I think it is very different from other things, but at the same time wouldn't require magic or a supercomputer to work well. I look forward to reviews.

I've never used the Lightswitch (or StarSense) myself, so I went and looked at the Manual for the Meade LS Series scopes.
You are right that it depends on knowing its latitude and north (and level), but it determines these values automatically. So while the internal implementation may be different, the practical result is the same: You set up the scope and turn it on. After a few minutes, it is aligned and ready to go.
I think that the future possibility of a pointing model is interesting, but I question how important it is. For visual use, I've had multiple samples of CG5 and CGE mounts. Since the release of the v4 hand controller, I've never had any of them fail to put the desired object in the eyepiece. For imaging use, it would be more useful. But for the cost of StarSense, you are getting close to the cost of imaging software that already includes a plate solve solution. I know that I've been plate solve synced pointing for years already. I don't event think about it.
The other thing that would be interesting is to use this for a guiding solution. You, yourself have already outlined my concerns about this, regarding flexure, on the LX850 thread.
When I first heard about StarSense, I wondered if there was anyone willing to pay a couple of hundred bucks just to automate pointing alignment (which takes all of 5 minutes, and only needs to be done once per setting up of the mount). It doesn't even do polar alignment for that price. But I've seen enough posters here with interesting reasons as to why they'd want this, that I believe that there is a market and it will make people happy (and, more importantly, more likely to use their equipment to observe).
This is all good stuff, but I just wanted to point out that Celestron was not the first to get there with a consumer level system. Meade beat them to it.

I agree with most of your points - mainly that the version 4 contoller does very well with 5 or 6 stars and a cge or cge-pro. If my equipment is already set up and hibernated from a previous imaging session - then there is almost zero time and effort getting right on target.
But any time I set up fresh it is a bit time consuming to find the initial stars for a 2+4 alignment - especially when using a ccd from indoors. I often use a video finder in such situations, which lets me do it all indoors using nexremote - but it still takes a while. If I were setting up repeatedly, as many do, and trying to get an imaging session going - the value would be even greater.
For new users I think there are many reasons scopes are hard to align - and big factor is not having a sense that the star in there is the one you think it is. The may think a 6th mag star in the sct is Sirius because they don't have the experience.
Another issue is that even with plate solving software - most of it needs to know the approximate location pretty well. I use maxim Pinpoint and it seems to require a pretty good starting position. But with this "where the heck am I" kind of alignment with starsense - there is a need for a blank slate alignment - and that would benefit from a plate solving system tailored to the optics and ccd in use. I don't know how many commonly used plate solving systems could do what this needs to do - so even having it on the laptop and paid for already - it may not work for the task.

After helping lots of people learn to use their equipment, I would suggest that the single biggest mistake that I've seen is that the finder is not collimated to the main scope. Countless times, I've seen someone point their finder at the right bright star, only to find it not visible in the eyepiece. When that happens, they tend to center the brightest star in the field, which is going to result in a poor alignment. They are always surprised when I align the finder for them and then align the scope, how obvious the bright alignment star is when it's in the field, The second most common error that I see on the Celestron mounts is that people don't realize the importance of using "up" and "right" to center the star. This results in pretty-close-but-not-great pointing performance.
StarSense will benefit users by avoiding these problems. But still, they are easily corrected user errors once they are known. The problem is, that without someone to help, it is difficult for new users to figure it out on their own.
As for plate solving with an imaging system, I have never had a 2+4 alignment result in pointing so poor that Maxim with Pinpoint LE could not solve it almost immediately.

Hi, I can't wait, I'm ready to buy one now but I'm confused about the release date. I had been reading it was march 2013, but now I looked on the Celestron site and it says preorders shipping June 2013. Which is correct.

I have used the Sky Prodigy and the Meade LS (6in and 8in) and both have their good and bad points. I find both are very effective for visual observation of variable stars, using the 130 mm Newtonian on the SP for a wide field view of brighter stars. The light mount and the telescope are not well suited to high powers. The self-align and subsequent GoTo performance is excellent. I really enjoy using the LS telescopes, especially since the firmware was improved. The hardware design is great, even if it was done by a bricklayer as someone joked! There are a couple of alignment problems: the motor training seems to need redoing rather too often (signalled by alignment failures) and the 8in appears to have a compass offset, so it points too far clockwise. The camera is quite sensitive and will, for example, fix on the much fainter star preceding Arcturus and so mess up the alignment. Also, as with other telescopes such as the Celestron GPS series, it will sometimes select alignment stars which are too close together to give a satisfactory solution for all-sky use. I stand over it during alignment, ready to head off unsuitable second alignment stars. For these reasons, I prefer the Celestron SP system and look forward to retrofitting it to my 8in GPS and CG5 (now with a Meade 8in).
Tom.

Neilson, I ordered mine 3 days ago and the site said shipping in April. Today I checked and it depends where you go some say June and some say July. Celestron must have discovered a couple bugs. Meade would have shipped it anyway. That's what I like about Celestron and Orion they at least try to have as few bugs as possible before releasing a new product. Russ

I suppose Wolfman could be right. I was thinking UCAC is like 8gb... but GSC is pretty small (~1 gb).
Either way, platesolving to a desired location would be cool hardware implemented.

Folks,
Keep everything in perspective..... so what if you have a trillion stars in the plate solving database.....the limiting factor here is the size of lens (it is small in this case)..... if you can not see the trillion stars....they do not matter. So a database of a couple thousand of the brighest stars is probably good enough.

Good point Frank. My only experience so far has been with my various scopes so I didn't take that into account.

It doesn't even do polar alignment for that price.
Looks to be similar to the new controllers, it should be able to do a ASPA after it scans and you have it properly calibrated to the OTA's FOV. I imagine thats a feature that would appeal to people that own mounts without it.
