North West Quadrant - 26th December
A pretty blank quarter of sun all bar a few filaments and small areas of plage. There are a few smudges which are the result of a couple of chips on the glasswork of my el-cheapo 2x barlow which was used for this pic 😶 - time for a new year barlow lens me thinks! Despite this i'm pleased with the way this image came out given the low altitude of the sun and the poor seeing that this presents. The focus feature in the Genika capture software really helps with this. The image was taken with a PST double stacked with a Lunt 50 etalon and a PGR Chameleon 3 camera, along with the very effective Daystar Interference Eliminator to tame the issue of Newtons Rings easily with minimal tilt to affect focus across the frame.
