Description

Looking for a portable and easy to assemble telescope for celestial viewing? Then the AstroMaster LT Series is just for you! The AstroMaster LT Series produces bright, clear images of the Moon and planets. Easily observe the belts and moons of Jupiter and the rings of Saturn with every one of these fine instruments. For breathtaking views of brighter deep space objects like galaxies and nebulae, we recommend the larger aperture and light-gathering ability of the Newtonian Reflector.
