Hi,
very very bad seeing ... but with lots of post processing managed to get something out.
80mm f/6 + Quark - ASI120MM-S And one of the proms The following ones would normally go to the bin. Taken with the C8. But just to show some small spots (or just darker cells?) in that area from first image. Still most sources are reporting now 20 spotless days. How big does a spot need to be before it counts?
Edit: seems these are called "penumbral spots". If so then they can't be used to calculate the Wolf number.
White Light - AstroSolar ND 5 (still seeking some ND 3.8 in that size) Solar Continuum - AstroSolar ND 5 Regards,
Paul
