CaK Full Disk – 8th August

8 Aug 18

For whatever reason I seem to have been neglecting calcium wavelengths lately, and often as the case here when the sun is blank in whitelight there is still detail to see in CaK, here regions of plage associated with active regions from a couple of

rotations ago are still clearly visible. Taken with the 40mm scope and homebrew CaK filter with the PGR Chameleon 3 camera.
