THE TELESCOPE:

This dobson with its 200mm mirror, is already a device for the DeepSky observation, many objects already show structures, spherical star clusters are dissolved in many single stars. The gain of the light collecting capacity compared to the 150mm optics is 45%, of course also a parabolic mirror from Pyrex is used. It has a resolving power of 0.69" to Rayleigh and the observation of the moon or the planets also reveals the finest details. For the sun, there is a thin filter, minimizing shading and increasing the contrast. The Rockerbox is made of multi-layered plywood, the tube is stored in Teflon bearings and the Rockerbox holds the tube safely and wobbly, but the tube can also be mounted on parallactic mountings with optional pipe clips.
