Celestron C90 Mak Spotting Scope

The compact and highly portable C90 Mak Spotting Scope from Celestron is a powerful spotting scope with a Maksutov-Cassegrain optical path, a 32mm eyepiece, and an erect-image 45° diagonal that also corrects the view laterally. Because the finderscope and the diagonal both provide corrected images, the C90 is an excellent choice for terrestrial as well as astronomy viewing.
