An unexpected break of the low cloud late on Tuesday afternoon meant I was able to grab a quick image of the sun when I got back from work. To my surprise the sun was birthing 2 new active regions. Taken with the 40mm f10 and a 2x Cemax barlow along with the home brew CaK filter. The sun was low and I needed to use 2x binning to bring the exposure time back up.
