Celestron Mak C90 telescope

The Celestron Mak C90 (model 52268) is a compact Maksutov-Cassegrain telescope with a 90mm aperture and 1250mm focal length, yielding a focal ratio of f/13.9. This optical design provides crisp, high-contrast views of the Moon, planets, and bright deep-sky objects, while also serving as an excellent spotting scope for terrestrial observation. The telescope comes with two Kellner eyepieces (20mm and 10mm) for magnifications of 62.5x and 125x, and a StarPointer red dot finder for easy target acquisition.

The OTA (optical tube assembly) is lightweight and portable, making it ideal for grab-and-go astronomy. It features a built-in lens shade and a threaded objective for optional filters. The included tabletop tripod provides a stable platform, and the accessory tray holds eyepieces. The C90 is compatible with standard 1.25-inch eyepieces and accessories, and can be mounted on any standard tripod with a 1/4-20 thread. This telescope is a versatile tool for both astronomical and daytime use.
