Sky-Watcher N 254/1200 Skyliner FlexTube BD DOB Dobson telescope

The primary aim when investing in a Dobsonian telescope has always been to get a large aperture without breaking the bank. Sky-Watcher's BlackDiamond Dobsonian embodies this ethos with a fresh perspective. Featuring a patented sliding rod design, transporting this telescope is a breeze. Moreover, this innovative feature enables flexible adjustment of the focus point by simply sliding the rods in or out.

Let's delve into the telescope and its mount:

This BlackDiamond truss tube Dobsonian boasts a 10-inch parabolic mirror. With 56% more light-gathering capability than a traditional 8-inch model, it strikes a balance between power and portability. Details in globular clusters become distinct, and under favorable conditions, nebulae reveal intricate structures. Thanks to its f/4.7 aperture ratio and a finely adjustable 2-inch focuser, this telescope is ideal for observing extended nebulae. Even planetary observation yields rewarding views, such as discerning Saturn's ring gaps and several of its moons.

Equipped with a smoothly operating Crayford focuser, precise focusing adjustment is a breeze. Additionally, a T2 camera connector comes included, though a camera-specific T2 adapter, available separately, is required for DSLR use.

Truss tube Dobsonians are favored by serious observers for their exceptional portability, and Sky-Watcher's FlexTube Dobsonians take this convenience to the next level. With only three tubes, they collapse swiftly for transportation, then extend effortlessly upon arrival at your observing spot. Despite its simplicity, the telescope remains rigid even when fully extended, promising stable collimation.
