Description

Sky-Watcher’s Flextube SynScan GoTo Collapsible Dobsonian series are the telescopes your mother warned you about. Big aperture, bigger attitude, with all the innovations that make Sky-Watcher the obvious choice when hunting for that Goldilocks zone where value meets desire. Ranging from the standard 8 to a whopping 16 inches in diameter, Flextube SynScan Dobsonians are precision engineered instruments that will allow you to easily find and enjoy viewing night sky treasures such as planets and the Moon, nebulae, star clusters, galaxies and much more. With its patented collapsible tube design, these Dobsonians are truly the ultimate in portability and performance which is crucial when travelling to dark skies to make the most of these impressively large telescopes. The elegant truss tube design was carefully engineered to combine ease of use, extreme portability, and consistent performance in an affordable package. Unlike other truss tube designs, the Flextube Dobsonian does not need to be disassembled between uses. It transports as two compact pieces (optical tube and rocker box) that can be assembled and ready to use in just seconds! It is easy to collimate once set up, and it holds its collimation throughout the evening and even after being collapsed! The patented Tension Control Handle allows users to add or reduce tension, thereby increasing or decreasing the friction between the optical tube and the sideboards. The patented Freedom Find dual encoder design allows the telescope to be moved manually whenever the user wishes - but with no need for re- alignment! The SynScan hand controller allows you to point your telescope to a specific object, or even tour the best objects in the night sky at the touch of a button!! The user-friendly menu system allows automatic slewing to over 42,900 objects. Even an inexperienced astronomer can master its variety of features in a few observing sessions. The Flextube SynScan series seamlessly combines the convenience and affordability of the traditional Dobsonian with the performance and precision of a computerized GoTo telescope all to help you in your quest for big aperture views.

  • Great Telescope
Style: Collapsible 10" Dobsonian
This telescope provides awesome views. Both pieces arrived unlike other reviews stating that they did not. It was easy to assemble but it is very large so not an easy option for portability unless you are dedicated to doing so. My only critique is the fact that the base is made from particle or MDF board. For a high level telescope I feel that the base which supports it should be made of better material, but time will tell. ... show more

  • Sky Watcher Flextube 8" 200P SynScan GoTo Collapsible Dobsonian Telescope
Style: Collapsible 8" Dobsonian
This is my first ever Telescope and I went up and back between this one and the Celestron StarSense Explorer 8 and I am sure happy that I made the right choice! This Telescope is simply beautiful! It took me 45 minutes to assemble and it was easy, I used the tools they sent. I don’t know why people are giving these bad reviews? Mine did t have a scratch on it, both boxes came with all the parts and the build quality is amazing! I will post an update in a couple of months. The only downside to this package is they send you 2 tiny wood screws for the controller holder and they do not work. I want two little bolts with nuts and washers and will stop at ace tomorrow. It is a quick easy fix! Otherwise I will definitely buy from Skywatcher again! And I paid 100% for this scope with my own money! If you’re thinking about a sky watcher, don’t listen to these bad reviews because mine is awesome. Go ahead and pull the trigger. You won’t be sorry.! Beautiful Telescope! ... 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

  • 1st Telescope, I chose a monster
Style: Collapsible 12" Dobsonian
So this will,sort of, be a live review. That is to say, I will add to the review, as I assemble...all the way up through initial setup. I let the box sit on my floor for a day... after seeing how much struggle the delivery guy presented... i wanted to wait a piece before tackling this mechanical job. Everytime I walked by the two monster boxes ...I could see the box shiver a bit... it was ready to be seen... and I was ready to see it in action. Unfortunately these things don't arrive ready to go. The good news is, it comes with all the tools you need to assemble it. The bad news is, like all products of this nature, those tools blow... naa, I'm kidding. It's two allen wrenches and a Phillips head. As far as materials, for the base at least, it's particle board. I can't see how this thing can be yanked in and out of vehicles, over years, without falling apart somewhat. Let's be real, particle board sucks flying dragon dorks. A little material science forthought can most certainly make this a more rugged item... and at this size and weight and most importantly <PRICE POINT>, this is where small accidents can easily turn into catastrophes. Anybody who had ever had the pleasure of assembling 80's furniture, knows of what I speak. So...a future DIY upgrade path maybe. Should not have to. Base install, step 1, make a cocktail. Step 2... follow the inst... wait, there are instructions? Sort of... as with all chineasium products... stuff must get lost a bit in translation because all of their "how to" sheets suck. However, there is enough illustrations that it's easily figured out. 20 minutes of casual mechanicing will see you through without drama. Only had one pre-drilled hole that was off a bit, but that was just on the middle hole of the lens holder... not a dealbreaker. So far so good... it's 1 am, time to stop this racket and do something useful... that's right, make another cocktail and watch astronomy videos 😉 Tomorrow, tube assembly... Hey...so remember that part where I said these things don't come reassembled? Apparently, I was only speaking of the base. Because I opened the box... and it was assembled. Nothing to do but put it in place. So I put it in place. Brought it out for one night of no-instruction, no-tuning, no-skill viewing. Who, knows... maybe I will have gotten lucky. Nope... zero luck. Couldn't see a damn thing. Read the manual folks. ... show more

  • So far so slowly good
Style: Collapsible 12" Dobsonian
I took 2 hours to set up the base for my 12", because I wanted to do it carefully and was misled by the instructions about the side on which to screw the bracing foot and handle. I was also disappointed that although the parts list had 3 handles for the 12", there were only 2. I could have used that extra handle for fetching and packing. Anyhow all's well that ends well. The barrel and optics were set up in negligible time even though I had never before seen that clever design. The 9x50 finder was quickly aligned with the top of a distant telegraph pole, on which a snail hawk decided to perch and pose unknowingly. Next will be the electronics after I set up a solar powered 12V d.c. supply. ... show more

  • Great telescope
Style: Collapsible 10" Dobsonian
I've been looking for a larger telescope for years. And now in a position to get one I chose this Sky watcher. Had a 4-in Bushnell for ever, and was not very happy with the quality. At some point I may splurge and go all out and get the 16-in version. But for now this is just fine for backyard viewing. I will caution that no power supply came with us. You will need to supply a plug and Supply or make some type of battery supply plug this into. ... show more
