I had progressed from a 3″ Zeiss Jenna refractor to an 8″ Celestron reflector to a 16″ Schmidt Cassegrain LX200 reflector, and I also had a small Meade portable ETX. The 16″ Meade is a fine robust instrument, and in moving from the slide-off roof shed to the dome I took the opportunity to change from an altazimuth pier to an equatorial one. This provided the ability to piggyback another scope, and I chose a Takahashi FS 128 5″ refractor with a focal ratio of 8, which would enable a considerably wider field of view than the Meade at prime focus.
