Do you use a binoviewer on your Lunt 60mm or other Lunt solar scope? Is there enough back focus? As it is I have to pull the diagonal out about 1 inch to focus my Baader zoom. It would seem there is enough back focus but I'm new at this.
What binoviewers do you like best?
Lunt 60mm/50mm DS
iOptron 8900 Cube Pro
Baader Hyperion Mark 4 8-24mm
Tele Vue 2.5x Powermate

Sorry, don't use them. Lots of people do though...

I do on occasion with the LS80, honestly spend more of my time trying to get the hang of imaging and processing. I couldn't quite reach focus straight through, but Harry Siebert makes optical correctors that will allow you to reach focus (including a 0X). A Barlow that increases outward focus requirements might work as well, I've heard that the GSO 2X does this. I bought a pair of pre-owned Denkmeier Standards that had one included, and have since acquired a "supercharged" Zeiss bino from Denis Levatić (might be on this board, I came across him on Cloudy Nights though) which is the bomb.
