INTRODUCTION

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.

Though Coulter Optical went Chapter 11 in 1996, they were purchased by MURNAGHAN Instruments, so life goes on!
