A couple of images from daylight yesterday-
Sol, sunspot AR2741 Sony a6300 on my Skywatcher 150P reflector. ISO400 1/400 sec exposure



I'm hoping that we have just reached the end of the last 11 year sunspot cycle as this is the first I have seen for a while and others have reported a possible increase in activity.

Daytime moon. 2 pane mosaic, same rig, ISO400 1/125sec.



A good daytime moon hangs in the sky like the Death Star doesn't it?
