1. Refractor based on Istar Optical 127mm F5.5 lens with internal ERF (BelOptik 125mm diam.) and GSO linear Crayford focuser. It's ready to install any etalon for safe solar viewing/imaging. I also used it with DayStar Quartk with great results.
2. Coronado SolarMax II 60 BF15 (it's unbelivable but front lens has 70mm diameter)
3. Lunt LS50Tha/B400 (modded to B500)+custom made 1,25" crayford focuser (not pictured).
Istar refractor is convertible to h-alpha scope using Coronado SM60 internal etalon. Proper adapter is in the set. It gives awesome views! With BF15 you don't have any vignetting.
