Managed to catch some rays today (despite splitting headache due to sinusitis). seeing was terrible, but stacking 400 out of 4000 frames worked quite well in WL and Ca-K.

I also grabbed one detail shot in H-alpha, catching AR 2635.

Not brilliant, but the best I could do under the circumstances. I didn't get the full mosaic data set because the scope was shaking too much in th erising wind by then (still imaging from the pavement across the road, as the sun is still just behind the trees from my more sheltered garden)
