Rated 5 out of 5

Perfect Choice to beginners

I was in my first Astronomy class. And there were about 6 more telescopes. I thought others would be better then mine. They looked amazing and bigger. But when we used them, my telescope was the most interesting for the people. Images sharply and easy to use. I recommended it to a 15 people i think.

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.
