SkyWatcher K100 Klevtsov-Cassegrain telescope tube

100mm (4") f/10 Klevtsov-Cassegrain Telescope OTA (incl. Smartphone Mount)

The compact Sky-Watcher K100 Klevtsov-Cassegrain optical system features an interesting catadioptic design, consisting of a primary mirror and a secondary mirror, with a small correcting lens in front of the secondary mirror. This reduces the focal length of the telescope into a relatively compact format, ideal for observing double stars or surface details of the Moon or brighter planets. The telescope is equipped with a friction focuser with two focus knobs (patented design) that moves the primary mirror to achieve focus. A distance scale is also included to indicate the position of the focuser, allowing you to focus on objects at distances of 8m, 14m, and infinity. This focuser design allows for particularly fast focusing without much trial and error.

With the included smartphone mount, you can take pictures of the night sky. Make one.
