I recently was able to finally get one of these Celestron Starsense Autoalign been wanting one for a few months finally got lucky and found one on eBay and won it for $270 with free shipping.
For many of you who don't know what the Celestron Starsense Autoalign is or what it does I will explain below...
The Celestron Starsense Autoalign replaces the hand controller that comes with a lot of the GoTo Telescopes Celestron sells The camera replaces the finder scope.
With a Celestron Starsense Autoalign after preforming needed steps then you do the Starsense autoalign the starsense camera will tell the mount to slew to spots in the sky and capture the sky to help know where the telescope is and to make alignment a lot better then having to spend a lot of time getting the alignment perfect, while having prefect alignment isn't really important for visual use but for astrophotography alignment is extremely important it's the difference from being centered in the eyepiece and being centered if you were to connect a camera for imaging or being way off.
The Celestron Starsense is only compatible with select Celestron GoTo model telescopes and will not work on any mount not made by Celestron.
The Celestron Starsense saves a bit of work required like alignment rather then having to do it yourself the Celestron Starsense will do a lot of the work for you, however you do need to preform a few steps like, making sure the date/time and location are correct each time you use it, The first time you use the Starsense you will be required to calibrate this is only needed to be done once unless you take the starsense off and put it on another Celestron GoTo telescope.
There is a video Celestron has on YouTube which walks you threw the steps for setting the Celestron Starsense up.
