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... :grin: 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..

"Provides advanced mount modeling – the ability to align on numerous stars throughout the sky for extremely precise goto pointing accuracy."

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.

Yes ....but it can do a more detailed sky model for even more accurate gotos...uses more stars

Right?

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.

Sounds great to me
Anything to make setup quicker and gotos really precise is cool with me

Lets see whats what when the time comes

i have always dreamed of something like this well
it seems astronomy will never be the same again
anyone and i mean anyone even first timers can buy
a very large mount like Cge pro and C-11 Edge HD
and start no problems first time.

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.

Sounds great to me
