GSO telescope in the Newton 203/800 CRF system on the Sky-Watcher EQ5 assembly

GSO N-203/800 M-CRF OTA is a complete optical tube in the Newton system with the diameter of the main mirror 203mm and focal length 800mm (light F / 4). 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.

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. Assembly weight: about 22kg.
