Why a CAT?,t will open the depths of space to your gaze and allow you to visit the Moon, planets, and the strange and distant wonders of the universe. And you are not looking for just any telescope; you’re interested in a Schmidt Cassegrain telescope (SCT), whose full-color advertisements fill the pages of ast

The hand controller will probably display some rudimentary information about an object: that it’s a galaxy in Pegasus, for e
