This is the story of my Coulter 17.5" Dob (vintage: late 1980s). The Coulter is a rather simple 'scope in terms of its construction (and materials!), and many people may thumb their noses at such an instrument but, nevertheless it works quite well! Here I will describe the few modifications that have been made to increase its performance.
