Question 1

I'm abit confused with this device.  Does it take the place of the finder scope or attach to it?  Can this be used with autoguiders?

Accepted Answer

Takes the place of the finder. You can mount it in addition to the finder but the finder is no longer  used in the alignment process.

Question 2

Sooooo, this is not an auto alignment device if you have to manually align it, then hope it maintains what star you picked to go back to “realignment?

Accepted Answer

The StarSense accessory is indeed an auto-alignment tool.  However, as the camera and firmware cannot assume the the center of the StarSense camera is perfectly aligned with the center of your eyepiece, a calibration routine needs to be done when first installing to tell the StarSense precisely which pixel on the camera lines up with the center of your eyepiece.  This calibration is saved in the camera and only needs to be re-done if the StarSense bracket is adjusted or the camera is moved onto another telescope.  The StarSense looks at fields of stars, not individual stars, and it uses those fields to determine the exact center of the FOV for each alignment "point."

Question 3

Does this work with the Celestron CPC 925 Schmidt-Cassegrain?

Accepted Answer

According to the compatibility chart in the instructions it is compatible with the CPC models. I have a CPC925 also, but have it attached to a Nextstar6 evolution. I think because the evolution is a newer model I had to upgrade the firmware. Probably might have to upgrade it for the CPC. All the Celestron Schmidt-Cassegrains use the large bracket that attaches the camera to the scope. The camera slides off the bracket making it easier to attach bracket to scope. Once attached slide camera back on bracket and use the special long screw (bolt) that keeps camera on the bracket. Celestron website has firmware update with instructions on how to use. Celestron tech support was also helpful with email on how to upgrade. The picture attached to my original post shows the cables needed to upgrade the firmware and how to set up.  Good luck, I hope my cpc works after a year in storage, terrible clouds and fog in this area.

Question 4

Does this align accurately enough on a CGEM or an AVX for astrophotography with C9.5.  I need prescise and accurate goto, at times @ focal length 11

Accepted Answer

If you take your time and follow the instructions it should be perfect.
