Description

Sky-Watcher’s GoTo Dobsonian epitomizes Sky-Watcher’s dedication to innovative ideas, combining our exclusive collapsible optical tube design with the convenience of a computerized GoTo mount. The SynScan hand controller allows users to point the telescope at specific objects, or tour the night sky with the touch of a button! Most astronomers crave the large aperture of a Dobsonian telescope, yet the lack of computerized GoTo features can be discouraging for some users. Sky-Watcher tackles this by adding motors to a traditional Dobsonian base, giving astronomers the benefits of a computerized GoTo system. Sky-Watcher’s signature SynScan hand controller uses two easy alignment methods, ‘Bright Star Alignment’ or ‘Two-Star Alignment’ for quick and easy setup. Once aligned, the SynScan hand controller can point to over 42,000 objects, including a full catalog of Messier, NGC and IC objects, providing you with a lifetime of celestial observing! While Dobsonian telescopes have a reputation for large apertures at a low cost, they often come at the expense of portability. The GoTo Dobsonian fixes this problem using our exclusive collapsible optical tube, featuring a strut system with three 1” steel poles and chrome locking screws. The strut system uses preset indentations which place the optics in the same position time after time, maintaining collimation. Unlike other Dobsonians using truss-tube systems, Sky-Watcher’s GoTo Dobsonian optical tube does not need to be disassembled before transporting from one location to another. With the ability to collapse up to 36%, these optical tubes can be easily transported in the backseat of most vehicles. At the heart of every Sky-Watcher telescope are professional- grade optics. The GoTo Dobsonian is no exception, using borosilicate mirrors coated in quartz, titanium and silicon dioxide. This yields an amazing 94% reflectivity, vivid contrast and minimal vignetting to deliver an exceptional viewing experience. Unlike other manufacturers, Sky-Watcher has a policy of providing you with all necessary accessories to get started. 8”, 10” and 12” GoTo Dobsonians include a 2” Crayford-style focuser, with a 1.25” adapter and two 1.25” eyepieces (10mm and 25mm). Whether this is your first telescope or not, there’s enough accessories for every kind of astronomer.

Yes, it is big, yes it is awesome. Now for all you fans, something I did not know. Upon opening the box, the first piece of paper slipped out and indicated , "by the way your Sky-Watcher has built in Wi-Fi." I did not know they had started doing this. I almost bought the Wi-Fi dongle with the scope. I did not have a lot of time with the scope before skies stopped cooperating. I never even used the hand control, just my phone. Fantastic. The pic of the Orion Nebula was just with me trying to line up the phone with the eyepiece, we know that isn't easy, but time was an issue. In any case, the thing kicks butt and has its own Wi-Fi, not networkable, but just connect with phone. I love you Sky-watcher, you're my only scope. Edit. Many folks ask about tracking for astrophotography. Added last pic of Orion with my Pixel with 1:20 minutes exposure. So yes you can do some exposure, but probably not more than 30 sec. Re-edit. Has issues with the drive. Skywatcher support was quick and helpful and sent new base. Very hard to find that type of customer support. Good job! ... show more

    • Great Scope, Great Customer Service
Style: Collapsible 10" Dobsonian
Received my goto Dob and had a problem with the goto base. Tried resetting encoders, factory resets, but could not get it to get close to being accurate. Believing it had a bad encoder, I contacted Kevin at Skywatcher, and after explaining my problem he got a new base out to me quickly. That kind of customer service is rare these days. The telescope is an amazing light bucket, and comes with 2 Plossl eyepieces that are a good start for stargazing. The new goto base works amazingly well after a short two star alignment. All selected objects are nearly centered in the eyepieces after alignment. I have the Skywatcher wifi dongle and use Sky Safari 6 Pro as my goto software. It works great. I would highly recommend the 250p Goto for its cost, portability and light gathering capability. But the customer service is what will bring me back again for more Skywatcher equipment. ... show more

    • Great scope, just technical issues with features.
Style: Collapsible 8" Dobsonian
The scope is amazing. For nearby planets you can see the bands of Jupiter pretty well and make the main ring features of Saturn out pretty well. To be fair, your naked eye view is going have the planets look a bit smaller than a pea. You will see Jupiter and a half dozen of its moons in your total view - so that's neat. Deep space options are great views to capture on this scope. You aren't going to see colors and such, but you will see great clusters. If you want the coloring and all, you'll need to also invest in photographic equipment for long exposures. Now the downside. The motors had issues. This of course is a big deal since you need them to move the scope around. They worked great for a first couple of days and then would die after moving for about 3 seconds. Nothing would get them moving against except a hard reboot. The other big issue I had was with wi-fi connectivity just dropping constantly. This was even with having one of my access points with in 20 feet and no obstructions. Needless to say tracking goes crazy or just stops working. Alignment with the scope is okay - as long as the App works or you can see and properly identify some of the brighter stars. Unfortunately planets cannot be used with the on board alignment - that only happens with the App. End of the day the technical issues with the scope and unable to resolve them caused me to return it. ... show more

    • Multiple defects.
Style: Collapsible 10" Dobsonian
As a Newtonian telescope - it's a good value for the money. My issues were a manufacturing defect that made it very hard to turn in azmuth, a nonworking 'down' key' on the controller and getting an error message every time I tried to align it. Talking to tech support did not resolve any of these problems. And a word of warning - you need to be good at collimating because you will be re-collimating every time you use it. The Flextube does not return to the exact same position after you collapse it and extend it again. When manually pointing, the views I was getting were outstanding. If the thing simply worked properly, I would have loved it. ... show more

    • Just get it... you won't regret it!
Style: Collapsible 8" Dobsonian
I had been thinking of upgrading to this scope for a year before I did it, and I wish I could get that time back and just buy the thing already! NO regrets! Previously I had a 4.5" manual dob; it was a great starter scope. What I love about this one: 1) The tracking! It's great to be able to keep observing without having to manually track an object, especially at higher magnifications. 2) The goto synscan system: setup is amazingly quick and easy (2-4 minutes!). 3) The ability to seamlessly switch between goto and manual moving; yes, you can at any moment just manually move the scope and then go right back to the goto system without resetting! 4) The collapsible tube; the scope can fit in my Prius when collapsed; a cloth light shroud keeps it as dark as if it was non-collapsible (this is NOT included, but is a highly recommended accessory. You can make one yourself or buy one for not too much.) The only thing I did not like was the focuser was in need of adjustment, but that only took me about 5 minutes with an allen wrench and now all's well! ... show more
