CaK Sun - 29th December

After weeks of unfavourable conditions I was able to end the year on a solar high. After spending the day rebuilding the helical focus assembly on my Coronado SM40 tube assembly I switched the Ha filters for my homemade double stacked CaK filter, seeing was awful first thing on this frosty sunday morning so used a 0.5x focal reducer to try and tame the seeing a bit. It seems to have worked and i'm pretty pleased with this result!
