AR12592 in CaK - 18th September

The weather was frustrating today, it was gloriously sunny until the moment I looked through the scope when the clouds duly arrived.  The rest of the day was shooting in the gaps between the clouds.  The seeing wasn't too bad at times, and as a result I decided to get the 100mm Tal refractor out with the CaK filter at 2000mm focal length.  Taking 1000 frame files meant the stacking software had something to work with, and as a result I was quite pleased with the resultant image of these small spots.  The PGR Chameleon 3 camera was used.
