Abstract

So you’ve got a great big Dobsonian. How do you get the most out of it from an optical standpoint? Are the mirrors aligned properly with your inserted eyepiece? Do you want to evaluate the optical quality of your ‘scope? This chapter addresses all these issues and helps you get the maximum performance for your hard-earned investment. Let’s begin with the age-old Newtonian chestnut – collimation – and how best to execute a near perfect alignment of your optics.
