23rd Dec... There are many sunspot groups on the Sun at the moment.

This image is a single exposure with a Canon 550d camera attached to a WO 81 mm refractor with Herschel wedge and 540 nm filter. The spots are numbered. Also some faculae. There was a M1.3 flare around AR2908 0n Dec 22nd. Thanks for viewing.

Thanks for the update, appreciated.
I’m still out of action until the replacement USB3 cable arrives.
