AR12629 in CaK 4th February

While todays seeing wasn't great there were moments when it showed some promise, to the point I decided to get out the 100mm Tal100R refractor.  Stopping this down to 80mm with a Beloptik tri-band ERF and running at 2000mm focal length I was able to get some close up views of this departing active region revealing some quite small scale detail. Taken with the homebrew CaK filter and the PGR Chameleon 3 camera using 2x2 binning.
