Skywatcher AC 150/1200 EvoStar OTA

Description

Multi-coated CDGM crown and flint optical glass elements power the Skywatcher AC 150/1200 EvoStar OTA large-aperture achromatic refractor optical tube assembly. Designed with an f/8.0 focal ratio, this 150mm (5.91 in) aperture telescope features a 1200mm focal length, delivering 0.77 arcseconds Dawes resolving power and reaching magnitude 13.6 for high-resolution planetary and lunar visual observation.

The Skywatcher AC 150/1200 EvoStar OTA utilizes an air-spaced Fraunhofer doublet objective with multi-coated anti-reflection surfaces and an unobstructed 0% central profile. Its 1280mm aluminum tube features internal glare baffles and a 2-inch rack-and-pinion focuser with a 1.25-inch adapter and external T-2 camera threads. Weighing 12.50 kg (27.56 lbs), this 6-inch refractor OTA mounts securely onto heavy equatorial saddles via heavy tube mounting rings and a 44mm Vixen-style dovetail plate.

Key Features of Skywatcher AC 150/1200 EvoStar OTA

6-Inch Fraunhofer Doublet Optics & T-2 Camera Threads

The 150mm objective lens captures crisp planetary disks, lunar rilles, and tight double stars with high contrast. Equipped with a robust 2-inch focuser and integrated T-2 camera threads, this Sky-Watcher refractor OTA supports visual and photographic magnifications from 21.4x up to 300x.

2-Inch Rack-and-Pinion Focuser & Heavy Mounting Rings

Flexible mount integration is essential for heavy refractor optical tubes. The Sky-Watcher EvoStar 150 OTA features direct T-2 threads on the focuser drawtube for secure camera attachment. Supported by heavy-duty tube rings and a 44mm Vixen dovetail bar, it attaches firmly to custom observatory mounts without drawtube flexure.
