At only 24 inches long, this telescope is still portable enough to be taken to dark skies and set up by a single person. It’s an ideal instrument for serious astrophotography. The Celestron C11 provides excellent, high-contrast views and can perform at very high magnifications. It is equipped with Celestron’s patented StarBright optical coatings, which visibly increase contrast and light transmission for brighter deep space images and shorter exposure times. With StarBright, you’ll be able to discern subtle details while viewing the Moon 2'' diagonal 40mm Meade eyepiece The CGEM™ mount has a fresh, attractive, bold appearance and is capable of carrying Celestron’s higher-end SCT optical tubes securely and vibration free, which is ideal for both imaging and visual observing.
