Sky-Watcher - 10-Inch Flextube 250P Dobsonian Telescope
- The Sky-Watcher Flextube 250P 10-Inch Dobsonian Telescope provides the best price point for a stunning 1235x light gathering power and 10" aperture, something that would often be more expensive in other optical tube designs.
- The user doesn't need long setup times, worry about transporting the telescope or loss of collimation due to the collapsible nature of the Flextube design!
- Sky Watcher's Radiant Aluminum Quartz (RAQ) coatings ensure light reflectivity reaches 94% for maximum visual quality.
- Focal ratio of f/4.7 makes the optical tube great for observing deep sky objects with lower surface brightness but also works great for planetary observing as well.
- Installed teflon bearings ensure smooth and accurate control for the user to view the intended object.
- Comes with a 2" Crayford focuser with 1.25" adapter to accommodate almost any eyepiece.
- Included accessories are a 1.25" eyepiece adapter, 2" eyepiece adapter, dust cap, 8x50 finderscope and 25mm and 10mm eyepieces.
Sky-Watcher Flextube 250P 10-Inch Dobsonian Telescope
The Sky-Watcher Flextube 250P 10-Inch Dobsonian Telescope represents a perfect classic dobsonian with a decent aperture and convenient use without breaking the bank! It is one of the best designs to get a remarkable 1235x more light gathering power than the human eye at a great bargain when compared to other optical designs like refractors or Schmidt Cassegrains.
The collapsible design is the flagship advantage of the Sky-Watcher Flextube series not only because it provides the user with portability and a quick setup time, but also because it retains collimation!
In addition to the ease of use of a dobsonian design, Sky-Watcher has designed the 10" Flextube 250P with extra portability in mind as well as optical coatings to maximize light transmission to achieve 94% reflectivity! This is due to their parabolic borosilicate primary mirror coated with Radiant Aluminum Quartz (RAQ) coatings. In essence, this makes the 10" Flextube great for both deep sky and planetary visual use.
To give the optical tube ideal support and control, Sky-Watcher has installed Teflon bearings for smooth and easy Azimuth slewing and a tension control handle to lock the telescope in its intended target. The telescope can accommodate both 1.25" and 2" eyepieces with the 1.25" adapter included with the 2" Crayford focuser.
Included items consist of a 1.25" eyepiece adapter, 2" eyepiece adapter, dust cap, 8x50 finderscope and 25mm and 10mm eyepieces.
