Very nice details, I assume it is a single frame.

Yes just an afocal single frame. The sun skirts the neighbours’ rooftops currently so it was quite difficult to get something half decent. Hoping for better conditions and positioning tomorrow.

Some more from today, better conditions and a more stable tripod due to it being retracted. AR 3190 is ridiculous in size. The black umbral spindles are really visible. Might be time to save for that Ha scope. I have also been thinking about getting the new continuum filter to see if theres any visual improvement although probably more detectable through a camera sensor.

Great captures, a continuum filter would help. I alway's use one with WL. 

I have the 10nm one which is great a bringing out faculae but FLO now sell the Baader 7.5nm which would improve contrast. Very tempted!
