Description
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.
The back of the scope has male SCT threads.
