It was almost forty years ago when I sold my 6-inch Criterion RV-6 Newtonian reflector. Life became really busy and I just didn’t have time to observe for several years.
Earlier this year (2017) I decided to replace the RV-6, with another 6-inch reflector. I really didn’t need another telescope, but you know how that can be.
The telescope came with a bag of Bob’s Knobs thumbscrews, but I had not installed, until this weekend. It was very easy, replacing one screw at a time and collimating after each replacement.
The 6-inch reflector:
In the days of yesteryear, a 6-inch reflector was the workhorse of amateur astronomy, but in recent years has lost favor among the amateur astronomy community. Not so fast!
Please consider: The 6-inch reflector is reasonably easy for most anyone to handle, and has good light gathering capability. The venerable six is an excellent all purpose telescope, especially with an f/6 focal ratio.
