Orion 150mm Maksutov-Cassegrain Telescope Optical Tube

Explore new vistas of the celestial landscape with the superior resolving power of Orion's 150mm Maksutov-Cassegrain. The long focal length coupled with a wide 150mm aperture produce exceptionally crisp, high-power views of the Moon and planets, as well as smaller deep space objects like globular clusters and brighter planetary nebulas. This Mak-Cass OTA is an ideal high-power specialist for both observational astronomy and astrophotography.

Not limited solely to nighttime activities, the versatile 150mm f/12 Mak-Cass OTA can be used during the day for great terrestrial views when used with optional eyepieces and a 45° correct-image diagonal (sold separately).

The 150mm Mak-Cass telescope's meniscus lens is fully multi-coated for maximum light transmission so views and images are delightfully sharp and high in contrast. Its long focal length of 1800mm (f/12.0) belies the telescope's compact tube, which measures just 17.75" long (including visual back), for excellent portability. The telescope's 2" visual back and included 1.25" step-down adapter allows use of both 2" and 1.25" size diagonals, eyepieces and accessories (all accessories sold separately).

The sturdy aluminum Orion 150mm Maksutov-Cassegrain Telescope Optical Tube is outfitted with rugged metal front and rear cells. With its low-maintenance, closed-tube design, you won't have to worry about collimation adjustments since the 150mm Mak-Cass optics are permanently and precisely aligned at the factory.

Weighing just 11.5 lbs., this powerful 150mm Mak-Cass works well on medium-sized equatorial and altazimuth mounts. A built-in, Vixen-style narrow dovetail mounting bar along the bottom of the telescope makes it easy to attach to compatible Orion mounts. Dovetail finder scope base accepts any Orion finder scope or reflex sight.
