If you are looking for a versatile Celestron telescope that allows you to make both terrestrial and astronomical observations, then the Celestron Astromaster telescopes are the ones for you. Each model in the Astromaster Series is capable of giving you the right image for observing nature and the sky.

The Celestron Astromaster telescope produces sharp and bright images of the Moon and planets. With all models in this series it is easy to see the moons of Jupiter and the rings of Saturn.
