It was getting late in the morning and the seeing conditions were deteriorating fast on an otherwise beautiful day.
Ha FD on the Lunt 60 with Coronado BF. This is a bit under sampled on the Basler acA1920-155um camera with a 1.5x Barlow. I usually use a 2.5x Powermate for a better match to the pixel size.

and I couldn't resist a quick image of the small active region in spite of the seeing. I didn't want to risk over sharpening in ImPPG, so the image is a little 'soft' as a result.

Thanks for looking.

A cracking close-up Stu, showing fine detail of the disintegrating AR.
Shame the disks aren't busier today, but the nice-long filament is interesting.
Thanks vm

Looks like it could be almost, one filament below that AR, nice.
