I woke this morning in the wake of 'Storm Frank' to a suckers gap - that band of clear blue skies that follows the passage of a cold front before the unstable air triggers off bands of showers. It wasn't much of gap, but it was enough for me to capture this full disk of our star taken in Hydrogen Alpha light taken with the Coronado DS40 at 700mm focal length with the PGR Blackfly GigE IMX249 camera. For such a low altitude sun the conditions were really stable and I was pleased with the result, especially as this is my last shot of the sun for 2015. Happy New Year everyone, I hope it is a good year for you with clear skies!

I took quite a lot of images with the 60mm scope at 1900mm focal length, but, with the poor seeing most were useless, apart from this one! Which, while far from perfect is quite easily the best of a bad bunch. Taken with the PGR Blackfly IMX249 GigE camera and the homebrew CaK Filter.

The sun was looking nice down at the blue end of the spectrum, and this full disk taken with the 40mm scope at 700mm focal length was good in riding above the poor seeing that was prevailing with the low near solstice winter sun.

The sun is surprisingly busy still, with a decent amount of large active regions and their sunspots. The seeing wasn't great when I took this image with the sun still very low in the sky only a day after the solstice, still, it is over a month since I was last able to image our star.
