Know Thy Dob

Part of the Patrick Moore's Practical Astronomy Series book series (PATRICKMOORE, volume 1)


Since the vast majority of Dobsonians on the market use Newtonian reflectors, it is fitting to begin this survey of this rapidly changing market with a discussion concerning the ins and outs of the reflecting telescope, so that you can get the most out of it and maintain it in tiptop condition. This chapter will discuss everything you need to know about how your Newtonian works. On our road to understanding, we’ll be dipping in and out of history to record the key events that shaped the evolution of the Newtonian into its quintessentially modern form.
