Which AstroMatster Telescope best fits your needs?

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.


If your interest is strictly watching whales, spotting birds, viewing nature, or checking out your favorite star or planet the altazimuth-mounted models are ideal. Alt-Az models have a convenient pan handle with built-in clutch for easy targeting and smooth motion. Models featuring the German Equatorial mount are a good choice for viewing stars, nebulae, star clusters, and planets. Built-in setting circle aids in locating these objects.
When used for astronomical viewing, AstroMasters yield breathtaking views of the Moon, Saturn with its ring structure, Jupiter and its belts and moons, nebulae, and star clusters.  Every instrument features all-glass optical elements as well as smooth-operating steel tripod mountings featuring manual motion controls. All models feature coated optics for enhanced image brightness and clarity.

Zoe J. ★★★★★

Set up was straightforward, and the 90mm aperture pulled in crisp views of Jupiter's cloud bands on its first clear night. I can already tell this is going to keep me busy learning the sky.

Penelope C. ★★★★★

Went from zero to spotting the moon’s craters in about ten minutes, and the 90mm aperture pulls in enough light to make Jupiter’s bands actually visible. The whole setup is light enough that I’ve been carrying it out to the backyard without any hassle.

Olivia ★★★★★

The telescope is surprisingly simple to set up, which was a huge relief for a total beginner like me. I was able to see Jupiter's moons on my first clear night out, and the views felt incredibly sharp.
