OK, you’ve decided to check out Astrozap’s 6" 8" & 10" Newtonian reflector telescopes. In contrast to telescopes, reflectors use a large mirror to gather light and reflect it to a smaller secondary mirror which then directs the light to the focalplane. In astronomy, size does matter, and the chief benefit of a reflector is being able to get a larger telescope for the same or less money than a refractor or catadioptric. This is particularly true with the Newtonian design.
