I'm really tempted by the Quark. I have a 127mm refractor I could use it with but my primary interest is double stacking my Lunt 100. I had been thinking of the chromosphere model but the discussion on exposure times in Alexandra's post got me wondering if I might be better off with the wider bandpass prom version for double stacking. Seeing here is typically not very good and I really like to keep exposure time to a minimum if I can. Would this compromise the benefits of double stacking too much? Any opinions on this would be greatly appreciated.
Thanks, Kevin
