Celestron 93969 SkySync GPS Accessory, Black

Ok, I got this because i was tired of entering my location and time EVERY TIME I powered my AVX up. I was used to a Vixen Sky Sensor 2000 which had an internal battery.NeWay, I got this and right away it connected and I was ready to start alignment. Also VERY convenient to be able to plug the hand controller into it and then into the hand controller receptacle on the mount. I’m using up all my available ports already.Having accurate time is handy for planet observing.It’s worth it alone to just fire up the mount and start aligning no matter where you setup, handy if you go to different observing sites.I do think this is on the must have accessory list !

I thought I would never need this. After all, I own a hand-held GPS and my phone has one too, so I know my home coordinates and even wrote them down on the telescope tripod leg. I found that entering the coordinates AND the time/date EVERY time I wanted to align the telescope took too much time, so I would just look around for the objects I wanted to view. I found that I was spending more time trying to find messier objects than it would have taken to enter the coordinates.The solution was to spend the bucks and buy this. It simply works. It does the heavy lifting and lets me spend the time doing what I bought the telescope to do–look at the sky.Yes it is expensive, but a lot less than the smart phone with it’s GPS, or even a good hand-held GPS, and the savings in time make it worth it to me.

Excellent if you don’t want to deal with the hassle of setting your latitude, longitude and time each time you turn on your telescope. It also has an aux female, so you can attach another device without need a splitter. I will say that it takes longer than expected to acquire all of the satellites and set the time. Overall a great addition to any Celestron telescope.

The sheer fact that I no longer have to manually input my location and current time makes my stargazing sessions even more enjoyable

I’m giving this max stars. It’s an addition I failed to purchase awhile back. But I’ll now say your telescope is going to like it and function even better in alignment procedure. Speeds things up and near automatic to use. Gets its power from the aux port.Mine is the compact 4SE and worked great this evening. Sky’s were more than hazy. Used an extra wide Meade 40MM eyepiece. Easily handles the larger Deep Sky. Sky so hazy even had difficulty centering the brighter stars in the finder!You have to go to the menu and find GPS, then turn it on! I was so slow fumbling in the dark gave enough minutes for the GPS to acquire satellites. This unit also puts in the correct time, easy to make a mistake here on the first outings.Area for Hercules Cluster wouldn’t show due to poor sky’s but area for andromeda our nearest neighbor came right in just off center of the low power eyepiece. Sizeable smudge. Polaris refused to show in finder so elected other bright stars on my auto two star alignment.Some areas of the sky did release some nice compact clusters, obvious in the view. Did after alignment check Polaris and shown well now in the eyepiece, but such poor sky conditions refused to show the dim companion fun to see even in a small scope. My Clave failed tho added contrast.Bad night but thanks to the GPS addition life was much easier and for some reason my Celestron behaves better with its use. I strongly suggest you add this one to speed up the alignment process. Likely find things are now a lot easier.
