Sky-Watcher Skymax 102 4" Optical Tube Only - S11510

2 In Stock - Ships Today if Ordered by 2pm EDT! (Mon - Fri)

The Sky-Watcher Skymax Maksutov-Cassegrains are the ultimate take-anywhere telescopes. Despite their small dimensions they pack a powerful punch. Their high-resolution, diffraction-limited optical systems are multi-coated to maximize contrast and image sharpness.

Note: This is the optical tube only and requires a mount or tripod.  It does not include a 2" to 1.25" eyepiece adapter.  If required, an Antares MDA is a good choice.
