Thank you for purchasing this Celestron Refractor Telescope. This telescope is a precision scientific instrument. With it you
will enjoy numerous objects in the sky—planets, nebulae, star clusters, galaxies and other astronomical objects.
This manual covers both the 70mm equatorial model and the 90mm model. The equatorial mount contains setting circles and
slow motion cables to make it easier to locate and track astronomical objects.

PERMANENT AND IRREVERSIBLE EYE DAMAGE MAY RESULT AS WELL AS DAMAGE TO
YOUR TELESCOPE. HOWEVER, YOU MAY ENJOY LOOKING AT THE SUN IF YOU HAVE A SAFE
METHOD OF DOING SO, SUCH AS A CELESTRON SOLAR FILTER.
