The new Sky-Watcher BKP 200 OTAW Dual Speed ••optical tube is a combination of a perfect parabolic mirror and two additional improvements. First, the Crayford 2 "extractor was equipped with a 10: 1 microfluxer, but the tube was shortened to extend the main focus to allow for smooth focusing in astrophotography in the focus of the mirror.
Sky-Watcher BKP 200 OTAW Dual Speed ••is a complete optical system tube designed for both astrophotography and advanced visual observation, both solar system objects, as well as clusters, nebulae and galaxies.
The tube can be mounted on any suitably strong astronomical assembly of EQ-5 or higher (HEQ-5, EQ-6) equipped with a dovetail foot, any manufacturer (Sky-Watcher, Bresser / Messier, Meade, Celestron, Vixen).

This device focuses a lot of light. Looking directly at the sun through this device can result in partial or complete loss of vision. For the observation of the Sun, we recommend the safest method of spectacle projection, that is, projecting the image of the target of our day star on a piece of paper.
