The 10inch Dobsonian telescope from Sky-Watcher is a Newtonian reflector telescope where the mirror is used to gather light. Designed for amateur and intermediate users, this telescope offers a large aperture, short focal length, good optical quality and great light gathering quality, all at an affordable price. In addition, its collapsible feature makes it easy to carry and move from one location to another.

The Sky-Watcher features a 10-inch objective mirror where on each primary mirror and elliptical diagonal mirror vacuum is deposited to the front surface and then again over coated with hard quartz (SiO4). After that again additional layers of Titanium Dioxide (TiO2) and (SiO4) are applied. This high-quality chemical treatment on the mirrors yields smooth surface that results in good contrast images with minimum color distortion. In addition to bigger 10-inch aperture and high-quality optics, telescope also has a fast focal ratio of f/4.72 that makes the telescope ideal for wide field deep sky observation like galaxies, nebulae, star cluster which otherwise not possible with other smaller telescope.
In addition, Sky-Watcher has included 4-element 25mm and 10mm Plossl eyepieces that provide increased magnification and a 52° apparent field of view. Reviewers report enjoying a clear view of M8, M20, M17 nebulae, and great Orion nebulae and also the outstanding view of Andromeda galaxy, planets, and the moon.
Sky watcher is using its revolutionary truss-support system, a feature that makes the telescope portable despite its large size. The system allows the optical tube’s front and back tube to collapse together easily by loosening the three knob and making it compact so that it can fit in the small car. In addition, for smooth horizontal and vertical manual movement, Sky Watcher uses a high-performance Teflon bearing system in both axes. Teflon bearings give better friction than ball bearing and also save the device from any automatic movement occurs due to small bumps or gusts of winds.
Easy to setup– Assembling the telescope is simple. Even a beginner user can assemble this 10 inch Dobsonian in less than an hour with the help of included easy to follow instruction manual without any expert.
Large aperture– Because of its large aperture and better optics Skywatcher, 12-inch Dobsonian performs extremely well in light polluted area. Reviewers report that they were able to use the telescope their backyard which otherwise was impossible for a smaller telescope because of street lights.
Collapsible– USP of this telescope is its collapsible feature, which makes the telescope easier for transportation and storage.
Viewfinder– Package includes 8×50 optical viewfinder that helps the user to search and locate desired celestial objects easily.
Need to collimate– Like any other reflector, Sky Watcher 10 inch Dobsonian telescope is also needed to be collimated once in a while. If you are not familiar with collimation, read
The article will help you in collimating your telescope in less than 5 minutes. Lots of YouTube video tutorial are also present online.
Highest useful magnification of the device is 600x, to take full advantage of this magnification we need some additional
Kit contains 5 different eyepieces of different length, a 2x Barlow lens and up to seven different filters.
This concludes our Sky-Watcher 10 inch Dobsonian telescope review, overall a spectacular piece of equipment for its light gathering capabilities, strong optics, high-quality optics and an excellent design. A perfect telescope for any amateur astronomer who is looking to observe deep sky objects but only has a limited budget.
