The resolution is really high, Vlad. However it seems the Quark was not tuned exactly at the H-a core - photosphereic granulation is easy seen.
Am I correct guessing the F/D was F/42 at the Quark etalon?

I know. I'll try to tune it better next session.
Focal length is very close to 5500, I measured it by limb radius. But reduser was used with little bit higher backfocus, so reduction is about 0.45. Looks like F/D was about 43-44.
