SkyWatcher 180mm Mak-Cass (OTA only).
. . The SkyWatcher 180mm Maksutov-Cassegrain Telescope exchanges the conventional front corrector plate with a convex meniscus lens which results in a smaller secondary mirror. Which increases contrast and limits the obstruction, while eliminating the need for periodic collimation. The scope is outfitted with a large 2" visual back and it also includes 28mm long eye relief eyepiece that produce a moderate magnification and a 90° star diagonal for more comfortable viewing when the OTA pointed at or near the celestial zenith.
