CaK Full Disk 26th April

It's that time of year for 3 months where I am able to observe the sun before I go to work in a morning.  Today had a little cloud initially but left me a quick gap to get the CaK full disk.  I seem to have been neglecting the shorter end of the spectrum lately, but for a quick full disk the 40mm scope and barlow allowed me to get this 2 pane mosaic of the disk.  Taken with the homebrew filter and the PGR Chameleon 3.  This is the second journey around for these active regions, and over the past week or so have been decaying.  I'm not sure they'll survive around for a third time with sunspots, but should be certainly possible to recognise them as an area of plage.
