The 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 EQ5 (CG-5) parallact mount offers exceptional stability and precision along with many other high-performance features that are useful for anyone, even an advanced astronomer. The assembly head reliably rests on a wide platform mounting stand made of stainless steel and equipped with a useful accessory table. The set also includes a level indicator (level), adjustment of the geographical width setting along with a micrometer scale and an azimuthal polar setter for the polarity star. The EQ5 also has engraved aluminum adjusting rings and microcontroller knobs. Mounting can optionally be equipped with a polar spot scope and drive in one or two axes. Weight: 22 kg.

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.
