Product Description
If you're looking for a dual-purpose telescope appropriate for both terrestrial
and celestial viewing, then the AstroMaster Series is for you. Each AstroMaster
model is capable of giving correct views of land and sky. The AstroMaster Series
produce bright, clear images of the Moon and planets. It is easy to see the
moons of Jupiter and the rings of Saturn with every one of these fine
instruments. For views of the brighter deep space objects like galaxies and
nebulae, we recommend the larger aperture and light gathering ability of the
Newtonian reflectors.
