Orion 6" F/4.1 Newtonian Astrograph Reflector Telescope

Orion's 6" Newtonian Astrograph is a fine imaging telescope, operating at a fast f/4.1 focal ratio and with a splendid level of optical quality. This telescope was designed with the goal of being ideal for the astronomer looking to capture high-resolution images of deep-sky objects with minimal exposure time, letting you maximize every hour of precious night-time that you can get with your scope set up and deployed! And to add to the efficiency the telescope is relatively lightweight at only 12.7 lbs, meaning that it can be considered highly portable and moved to whatever dark site you wish to use. This astrograph is equally well suited to visual observation of the same kind of targets.
