CaK Full Disk & M7 Flare 18th April

I was lucky enough to be able to capture todays M class flare using my homebrew CaK filter and the 40mm scope at f20 with the DMK31 camera.  I've been doing alot of work with this filter over the past week to try and increase and improve on the already good contrast, to shift ghost reflections etc,  this is working well as the image above shows, but, as with everything can always be improved further, and so still have a few more ideas to test out.
