Welcome to the exciting world of amateur astronomy! Your new AstroView 6 EQ Reflector is designed for high-resolution viewing of astronomical objects. With its precision optics and equatorial mount, you’ll be able to locate and enjoy hundreds of fascinating celestial denizens, including the planets, Moon, and a variety of deep-sky galaxies, nebulas, and star clusters. - Page 4 screws up through the holes in the bracket, then thread them the internal O-ring from becoming unseated. If it does become into the holes in the tray. unseated, you can remove the entire housing from the mount to locate the O-ring and reseat it. This is done by rotating the 5.

In conditions of good “seeing”, star twinkling is minimal and objects appear steady in the eyepiece. Seeing is best over- head, worst at the horizon. Also, seeing generally gets better after midnight, when much of the heat absorbed by the Earth during the day has radiated off into space.
