Bresser Messier 8" Dobson (4716420)

Bresser Messier Dobsonian Telescope is a real breakthrough. This powerful Newtonian telescope gathers a lot of light due to its large 203 mm (8") optical tube diameter. You can explore numerous celestial objects, including the Moon and the planets as well as the deep-sky objects. The telescope features parabolic primary mirror made of H-PZ33 low expansion glass. Forget about vignetting due to its Hexafoc focuser with a 65 mm (2.5") diameter. Large widefield eyepieces are supported by the big altitude wheels that easily carry heavy eyepieces. You only need to move the tube in its tube rings and balance the telescope within seconds. Moreover, these large wheels provide smooth and precise movement even at high magnifications.
This telescope system is versatile: if you need to use this telescope for astrophotography, you can remove the altitude wheels from the tube rings, attach a dovetail, and it is ready to go. Moreover, the focuser handles even heavy cameras tilt and shifting-free. Assemble and disassemble this telescope easily and quickly: the parts of the rocker box are connected with the standard metal furniture fasteners. That is practical for compact storage or transportation of the telescope.
