Stonyhurst Disk for 28th November 2020
Quite a lot of atmospheric turbulence today so high res views were quite poor but managed to get a full solar disk (composite of 2 frames) with Active Regions annotated.
A large sunspot region, AR2786 is seen.
The Stonyhurst Disk superimposes correct orientation, axis of rotation and position of solar magnetic poles.

ZWO ASI 174MM camera
Best 20% of 5000 frames.
Acquired with FireCapture
