Well I went up and personal on the sun this morning. AR 2741 and 2740 at 08.30 UT. Altair Astro 102 ED-R and Daystar Quark with the DMK 31 camera. But this time no reducer. I reckon one around 0.8x would be OK. Plus a quick shot in white light with the Baader photo film, continuum filter and IR blocker.
