A great starter telescope

The telescope itself is quite amazing and a great starter for people with a higher entry budget. The main use is of it is for visual astronomy but I have done some astrophotography with it and it works quite well. You can photograph lunar and planetary with it quite easily with it just not so much deep space objects due to no tracking function, but visual viewing it works great both ways.


The Sky-Watcher Classic Dobsonian Telescope 254mm/1200mm (10") has a "paraboloidal" primary mirror to eliminate spherical aberration and a four-arm, secondary- mirror bracket with fine supports (0.5mm thick), to reduce diffraction spikes and light loss. In addition, this model include a 2" focuser with a 1.25" adapter, allowing the use of either eyepiece size. This model also include the new feature-tension control handle.
