I've had one on preorder since 1/23/13. :/

Anybody have any updates on this? I'd love to get one, but I don't like ordering products that may never materialize--once burnt, twice shy.




If you want to order, just pick a reputable merchant like the sponsor of this BBS, Astronomics. Anybody worth their salt won't charge your card till the product ships.

Just because it ships doesn't mean it will work.

Which is why you don't want Celestron to ship this before they are ready, pull an "LX800" or an "LX80," that is.

No, but this makes two reasons why I don't want to order it, even if my card won't be charged:

1) I don't observe much during winter. I don't want it to arrive in mid-November so it can sit around till by next summer an improved version (by a competitor?) surfaces.

2) It seems they underestimated the issues with the product, and so I'm getting worried that they'll release it eventually and it'll still be buggy. There are some circumstances where being an early adopter is not the wisest thing...

That's exciting! I will be very interested to see two things: 1) For people who already are comfortable with doing quality 2+4 alignments, will the StarSense actually result in equal or better pointing accuracy? and 2) For people like me who live in white zones, will it be able to find enough stars to successfully align?

If the answer to both of these is YES then this is going to be a really big product for Celestron.

To jump on the bandwagon, mine is shipping today from Woodland Hills. I'll have it Friday with clear skies and no wind projected for the next week.

I have a CGEM DX and a CPC1100 - I will try it on both. On public out reach nights it may work out better with the CPC1100. Oh, By the way. I loaded the beta software on my CGEM DX and for the first time I'm able to use my guider. The mount is a little jerky now when I slew but I can live with that.

Hi,
I just downloaded the manual from the Celestron site and was reading it. I noticed it said that if your imaging you might want to add calibration reference points to improve accuracy and so it will better center your objects. It said if your just entering one it should be near the object your imaging. Otherwise you can enter up to 10 calibration reference points. It also recommends adding multiple calibration reference points when doing a Polar Alignment.

I will want to be adding about 4 calibration reference points each night. It wants you to manually slew to each reference point. This kind of takes away from the whole ideal of having an automatic alignment device. If I don't use the Starsense and manually align my mount, the mount will automatically pick and slew to each of the calibration stars for me. But not if I'm using the Starsense. I think its kind of crummy that I will have to manually slew to each calibration point I add. Plus I will have to decide where in the sky to slew to for each of these added cal. points. How am I supposed to know where the best places to pick are.

I think they need to do a firmware update already. It sure would be nice if you could just input the number of additional calibration reference points you want to add. Then it would pick where to add them and automatically slew to each one. Geez it seems like common sense would have told them to do it this way. And if you want to just add one in a specific area then you could manually slew to that area.

I'm guessing many of us plan to take some images and plan to use the Polar Alignment feature. It sure would be nice if this thing was Automatic on the added calibration points also, and not just on the initial alignment points.
I'm not going to like having to manually slew my mount to points from one end of the sky to the other 4 times. And I have no ideal where the best places are that will do the best overall good to improve accuracy or for the Polar Alignment.
I think Celestron needs to get back to work and come up with a firmware update to correct this.

Neilson, learn about plate solving if you're an imager.

What does that have to do with having to pick and manually slew to the multiple added calibration points recommended to do the Polar alignment. There's no reason why the Starsense can't pick and slew to them automatically just like it does when it does the initial alignment.

I thought starsense automated the whole alignment and calibration process.

Otherwise what's the point?

I agree with you.

In order to be really usefull for all users, Starsense should be fully automatic regarding slewing and centering of alignment and callibration stars.

Starsense should let the user select, if he wants so, the name of the alignment and callibration stars.

Sure it would be nice if the cal ref points were automated, however I don't think its going to be to taxing to manually slew the mount a couple of degrees each time from the original alignment. Remember the camera is a 40mm F2 optic so its seeing a huge patch of sky each time plus your not having to centre anymore stars in your eyepiece/sensor. Do that nine times in any given area I think your going to get some pretty darn good goto accuracy anywhere in the sky. Anyway if Celestron has anyone reading this board why not automate this feature next firmware update

There are no calibration stars.

What there are is calibration positions. The SS takes an image and plate solves it to get an alignment point where it knows the axis position and sky position.

There are two main align modes.

In SS Auto the mount slews to four points, takes an image at each and uses the position to get an alignment. If it fails to get an image it can solve it moves a bit and tries again. It will keep doing this a lot until it has 4 points. This is for GEMs, there are two points on each side of the meridian. In AltAz mode I think it uses three positions.

In SS Manual the user has to do the slewing to the positions. There's no need to move to any specific position, just a bit of sky that's clear. No need to look through the scope. Simplest is to do two positions on one side of the meridian, the two on the other.

A calibration position can also be added by simply selecting align and Add Calibrate position. SS takes an image of what it can see, plate solves it and adds the position to the mount model.

So if the object you are expecting isn't in the field add a cal position of what is. This will give a good position near what you are looking at and a subsequent move to it should be more accurate.

Bear in mind that this does NOT use calibration stars. It uses the sky it is looking at and does a blind plate solve.
