GSO N-203/1000 M-CRF OTA is a complete optical tube in the Newton system with a main mirror diameter of 203mm and a focal length of 1000mm. It is a versatile astronomical instrument that allows to conduct very advanced visual observations and astrophotography. It is equipped with a 2-inch focuser with a reduction of 1.25 inches with a microfitter 10: 1 , allowing the use of both standards of eyeglass frames and very precise focusing.
As far as the observation possibilities of this tube are concerned, it can be used to observe objects of the Solar System (Moon, planets, asteroids, comets) as well as nebulae. In its range there are several thousand nebular objects (all objects of the Messier catalog and an important part of the NGC catalog).
The optical tube can be mounted on any assembly with stiffness class EQ-5 or higher (HEQ5, EQ6, with GOTO or without), through the standard dovetail link in the Vixen / Sky-Watcher / Meade standard. Optical system
