Your cart is empty.The Celestron StarSense Autoguider is an all-in-one accessory that makes using your telescope easier and more rewarding than ever. This powerful, compact device connects to your Celestron mount to enhance its pointing accuracy and help you create sharp, long-exposure images with ease. Whether you’re an experienced astroimager or just starting in the hobby, adding this game-changing accessory will ensure you have more quality time under the stars. The StarSense Autoguider features a high-quality 4-element optical design devised by the famed optical designer Mark Ackermann, a highly-sensitive Sony IMX290-DLL monochrome CMOS image sensor, and an onboard computer working together to provide exceptional guiding accuracy and deliver sharper images. The StarSense Autoguider, with no user input needed, can align your telescope to the night sky in about three minutes. Celestron’s patented StarSense technology “sees” star patterns overhead and matches them to its internal database to automatically orient the telescope. The StarSense Autoguider dramatically simplifies the polar alignment process when used with a German equatorial mount. This accessory’s precise GoTo places your celestial objects in the center of the field—even if you’re using a high-powered eyepiece or today’s small imaging sensors. This accessory eliminates the need for additional accessories when autoguiding, providing tiny adjustments to the mount’s tracking to keep your target locked in over long exposures. The StarSense Autoguider works with Celestron CGX-L, CGX, CGEM II, Advanced VX, CPC GPS XLT, CPC Deluxe HD, NexStar Evolution, and NexStar SE computerized mounts. You can control this accessory via your NexStar+ hand control, CPWI telescope control software via a wired PC connection or WiFi. The autoguider also works with the rest of your Celestron accessories for a seamless solution that fits in perfectly with your telescope setup.

I’m really happy with the StarSense Autoguider, it’s making my life much easier for imaging with my AVX mount. I’m using a Canon camera with an 8†EdgeHD and was looking for a way to simplify my setup, as I don’t always want to use a PC, especially when I travel to dark skies.Love the automatic alignment feature, and guiding results have been great so far. I wasn’t planning on utilizing the polar align function, but I tried it out tonight and it was super cool! I was able to “dial in†so that I was polar aligned super accurately and it only took a few minutes. Oh, did I mention it looks really cool mounted on the telescope?Setup was easy, although it did take some time to go through the manual to get oriented. I had to update the hand control firmware first, which wasn’t a big deal. I had been playing around with the CPWI software in my backyard with my setup, so I was familiar with how that worked, I just needed to download the most recent version of that too. I like the guiding graphs in CPWI.It was a little more than I hoped to spend but has been worth it because it has been so fun to use. Kudos Celestron!UPDATE: I read the comments about people getting a box that was previously opened – mine was too, so I called Celestron Tech Support. They said the reason why the box was opened is that they did a 100% QA inspection before any units left the warehouse. So it's a good thing!

I was very excited about the idea of the product. I have Celestron 8†nexstar evolution telescope.But - after many hours reading online forums, updating software, trying with both hand held controller and phone app - I would get constant errors. Sometimes it would say plate solve was successful, at three different locations, but then would say alignment error too large. Or it would say it’s aligned, but the pointing would be way off.Eventually, gave up and bought the older AutoAligner. It worked on the first try, and works every time. Returned this item.

Tonight was my first clear sky with the AutoGuider, but I could not get it to work right. I have an email in to Celestron for help. I used the Autoalign for over a year and wanted something better. I am guessing that, even after all the reading about what to do, I still did something wrong or in the wrong order and this can be fixed. If not, it gets returned and I put the autoalign back on.UPDATE: I was ready to return it, but after still another factory reset of the mount and SSAG, I have been able to get it to work. Objects are not always centered, but close. To turn on autoguiding, you have to get into the SSAG menu and click it on. Then, when you want to goto another object, you have to turn it off (the back button will turn it off), then slew to the new object, then go back into the SSAG menu to turn on autoguiding. Yes, you have to do all that for each object you goto. With a little practice, it was not too bad. So far, I am inclined to not return it. I still need to practice ---just waiting for clear skies. When it works---I like it! So, going from 1 star rating to 3. For now.Update: I sent it back for a refund. There were instances after a successful alignment, that it would slew to one object, no problem, then go to another object and it would start a slow drift upward (sometimes downward) without stopping. I had to stop it, then start all over again with a new alignment. Enough of that. I sent it back for a refund. They said they would have sent me a new unit, but if there were any issues, no refund since the original 30 days would be passed. Maybe I'll wait a few years and see if the reviews get better and try again.

I have a Celestron C-11 SCT on a Celestron CGX mount. I use a ZWO ASI178MC-cooled camera with a 2-inch mount. I do only astrophotography and have no visual capability. I have used the StarSense alignment camera since it came out. The StarSense Autoguider is a direct replacement as far as mounting and cabling is concerned, so it mounted and plugged right in. I use Celestron's CPWI software to control the mount. I fired it up and it recognized the SSAG immediately. I ran the calibration routine to calibrate the SSAG to the telescope and then did the 4 point auto alignment. The scope aligned and was ready for use in just a couple minutes. I selected several targets and slewed to them to test the SSAG's "goto" ability and found it to be dead on for each target. I selected a target and enabled "autoguiding" and did a 3 minute exposure. The autoguiding failed. Instead of pancakes, I got eggs for stars! The same test using PHD software and the Orion ST-80 telescope I have been using for guiding worked perfectly. THE SSAG WILL NOT ADEQUATELY GUIDE A 2800 MM FOCAL LENGTH TELESCOPE. Researching the problem I find that the ratio between the SSAG focal length and the C-11 telescope are too great. I suspect the SSAG would work fine on a shorter focal length, but mine is simply too big! Returning the unit.

Very useful for setting up your Celestron telescope. Had no problems and the target just appeared in the centre of the eye piece and stayed there.Installed on Celestron Evolution 8.
