Digital Camera World Verdict

It's rare to see affordable telescopes like the AstroMaster 70AZ. Although the manufacturer Celestron makes many cut-price telescopes aimed at beginners, this refractor has something unusual about it. Although its 2.7-inch/70 mm aperture is common at this price, the length of its optical tube is not. With a focal length of 35 inches/900 mm, it means a focal ratio of just f/13. That's no good for faint objects deep in the cosmos, but it is great for brighter planets and the moon.
