Dobson Telescope Drive

Introduction

        What was inspiring for this project were countless hours spend with the telescope in the open air. It is natural for amateur astronomers to aspire for more beatiful view in an eyepiece. Unfortunately appropriate equipment is very expensive. The best quality to prize ratio have the simpliest constructions, for example newtonian telescopes which are big and heavy. They are usually mounted on Dobson mountage, so they are not as handy as the ones equipped with equatorial mountage.
