Celestron 93969 SkySync GPS Accessory, Black

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.

This makes the set up much easier. It automatically adds the date and time and provides you with gps coordinates which you then punch in.

It works great. I needed this to make set up faster.

UPDATE: It has now been a year since I obtained a new unit directly from Amazon. And I am so glad I did! While the SkySync GPS is not absolutely necessary or perfect, I love using it in conjunction with my StarSense accessory. Combined, the two save a fair amount of set-up time. This is especially useful when in new locations, or when other people are around. You basically just turn on the scope, and let it do its thing. I use that recovered time to get other things ready, and friends/family don't have to sit there watching me struggle to align my telescope. Plus, it is cool to watch the hands-free alignment process! Considering my initial unit was a dud, and I now have a year of positive experiences, I am raising my review of the SkySync GPS to 4 stars... Because I travel a lot with my Celestron 8SE, I was really excited to get a Sky Sync GPS to go with the StarSense accessory. However (like others have reported), it only worked correctly at first, before promptly malfunctioning. After that, it would act like it was working- but provided grossly inaccurate date, time, and location information. And the included instruction sheet (if you can call it that) is worthless. Best I can tell from other online reviews, is there is some sort of internal non-replaceable battery that dies if it sits unused for too long. I purchased from a third party Amazon vendor, so perhaps mine was old stock. One person said Celestron told them it could be recharged by leaving the mount plugged in and turned on for 24 hours. But I didn't want to chance it while the return window was counting down. So it's being returned (no exchange was offered), and I will try again with a new one directly from Amazon. It was cool while it worked- but shame on Celestron for marketing a product with such an inherent weakness, and not providing basic operating/troubleshooting information. Fingers crossed the next one will be better... I really want to like it!

The missing link to the automatic telescope alignment procedure. Can be finicky. Should have 3 satellites to get a location fix. A clear sky to view the satellites. And a way to get the information to the software directly. Usually plugs into the mount, as does the WiFi module. Then everything goes to the computer and turns into controls to locate the telescope and the objects desired! I think you can plug directly into the mount from the computer, an Ethernet connection. You still have a network but it’s a local area network, LAN. Then the computer only has to connect to the world network if your software is on the world network. If you have the software then everything is right there on your computer. Storage space is a concern. But you can now get 1-5 TB of RAM on a USB C flash drive! Yet HDR video can be 1GB per 30 sec. Still, that’s a lot of frames to stack up. And Fine tune focus. Very easy to use. Weights nothing. Not sure about battery life or compatibility with other telescopes other than Celestron. Quality is built well. I hope the electronics inside is built to take the outside.

GPS adapter for my power telescope really like it because makes it easier to locate where I am in any place I decide to set up my power telescope

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.

You can’t see it on my telescope, but the picture is intended just to show that I take my telescope travel seriously! This GPS unit is a HUGE timesaver during setup and helps me get hyper-accurate positioning for tracking and Astro photography. The time saving alone makes this unit well worth the money. It’s small and fits out of the way, and I have mine secured to the mount. Now that I’ve had this GPS unit, I’d never want to be without it.

I initially considered this to be a waste of money since you only need it once at the beginning of each session and you can 'easily' manage to supply the required info manually (using a phone app for location/time) However, the manual method is prone to mistakes (particularly if you are a bit tired at the end of a day and operate from more than one site) not helped by the Americans inexplicable reversed date format (gents, if you are going to reverse a date, do a proper job and make it an ISO format! 'yyyymmdd') ... and after several failed attempts the process gets tedious and eats into your observation time. Cast all that hassle away - plug the SkySync GPS in, wait for the sync (whilst you are fitting your diagonal and choosing your eyepieces) , pick your stars for the alignment and then, if you wish, you can unplug it and put it back in the box - the GOTO will keep the details until you power cycle it. Forget the price, think of the value.

Perfekt att slippa knappa in min position

Prodotto come da descrizione. Fix rapido dei satelliti. Perfettamente compatibile con montatura celestron C8 SE Nexstar+.

You really don't need this for the telescope to work but manually entering the data every time you turn it on is so time consuming. By the time you set everything up you want to start observing, not have to then worry about entering data that you can make a mistake on. With this there is none of that worry. Definitely worth it in my opinion if you can afford it.

この機能が追加されると、望遠鏡のセッティングが早くて良いですね♪ スターセンスとセットで使用すると、アライメントがフルオートに＼(^_^)／ 便利です❗
