Grab yourself a bargain with this old stock Skymax Maksutov-Cassegrain 150! This particular telescope has been tested under the sky. In as-new condition, complete with original packaging and accessories. This telescope is exactly the same as the new version but has gold paint instead of the black found on the current model.

The Sky-Watcher 150/1800 Skymax Maksutov-Cassegrain is a compact and powerful optical design that combines a front meniscus and two mirrors. As the optical tube is closed by the meniscus, the mirrors are protected from atmospheric agents such as humidity and dust. Also a closed tube does not suffer from tube currents that limit the resolution power.  

The tube is compact but the focal length is long, allowing high magnification with the medium focal length eyepieces.

The Maksutov-Cassegrain telescope is ideal for high resolution observations and astrophotography. At direct focus, the moon and the sun (using a filter) will fit in a full frame camera. With a 2 x Barlow lens and a planetary camera you will get the right pixel scale for imaging planets and the craters of the moon.

The 2" focuser makes this telescope suitable for a vast array of accessories.

The meniscus is fully-multi coated for an improved light gathering performance.
