Skywatcher SWDOB200 DOBSONIAN Telescope is a classic 203 mm Dobsonian reflector designed for bright, detailed views of deep-sky targets such as nebulae, star clusters and galaxies. Its simple tube-and-base design uses two mirrors and a swivelling, tilting mount to make observing straightforward, while the 1200 mm focal length and f/5.9 focal ratio provide a wide field of view and strong light gathering.

The optical tube assembly features a borosilicate parabolic primary mirror with an aluminium coating for 94% reflectivity, plus a secondary mirror obstruction of 6% by area. The Skywatcher SWDOB200 DOBSONIAN Telescope includes a smooth single-speed Crayford focuser for precise focusing, along with a 1.25" adapter, 90¡ diagonal, 25 mm and 10 mm Super Kellner eyepieces, and a 9x50 finderscope.
