## Overview

The SkyWatcher Flextube 250 SynScan Dobsonian is a 10-inch large-aperture, collapsible telescope featuring built-in WiFi for smartphone GoTo control, all-metal gearing for precise tracking, and fully multi-coated 94% reflective mirrors. Its innovative collapsible design enhances portability without compromising collimation, making it perfect for serious amateur astronomers seeking powerful optics combined with modern convenience. The package includes essential accessories to start exploring over 42,000 celestial objects right out of the box.

## 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.

Review: What is not to love (first review) - 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!
Review: Just get it... you won't regret it! - 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!

## Questions & Answers

**Q: These all show optic viewers, can they be connected to tablets / smart phones etc.?**
A: Yea, you can just have a camera directly hooked up to the scope (without using an eye piece) and then have the camera hooked up to a laptop or tablet or w/e.

**Q: Will this telescope track an object as it moves across the sky? I'm wanting to do 3-5 minute exposures continually for 3+ hours**
A: Yes it will track. Not sure if the tracking is smooth enough for 3 to 5 minute exposures. I have had mixed success with 30 second exposures. The altitude and azimuth motors sometimes seem to go in a step function mode. All in all I am pretty happy with the scope but if I had to do it over again I would get an 8” on an equatorial mount. It would be lighter, more portable, easier to set up on a wet uneven lawn and more accurate tracking

**Q: How powerful are the motors on the sides of the tube for tracking purposes?  does camera/smartphone weight move it easily?**
A: I noticed that I can generally have exposures of up to 30 seconds or maybe even a minute before blurred lines become an issue, depending on the location of an object.  And this is with a Nikon D5100

**Q: how can one use a projector to show many people with sky watcher telescope?**
A: use a usb telescope camera. send to laptop computer.  and then use display clone from the laptop computer output HDMI to the HDMI input port of the projector

### ⭐ So disappointed
*by W***O on January 13, 2026*

The box arrived damaged with a hole and scratches. The secondary mirror adjustment screws and center screw were seized and could not be loosened, making the telescope impossible to collimate. The back of the secondary mirror was dented, raising concerns that the product was not new. I had to disassemble, repackage, and return the telescope, which took a lot of time. Overall, I am extremely disappointed.
