Description

Another large and very active sunspot region. This one estimated to contain about 19 separate sunspots with 80% flare probability covering 400 MH, more than twice the surface area of Earth. Only using an 100 mm off axis OD5 filter on a 14"Dobson, so no chance of seeing the flares - tempting to invest in a Quark!!

50% of 10,000 frames stacked in AS. This time adjusted curves in IMPP and sharpened and colorized in Photoshop (no Registax). Had less problems with line artifacts this way.  Bad seeing, due to ground head and fast jet stream, but managed to find a window of reasonable quality.
