Brief Sunshine - 2nd August
Seeing was awful, but I did manage to get some imaging in briefly before the clouds set in. Far from my best, but better than nothing!
G Band And CaK Sunshine 23rd July
A bit of a comparison with these 2 wavelengths at the same image scale:

CaK Sun 13th April
Fishing for gaps in the cloud again and just enough time for a full disk, although high cloud and haze meant the proms were not revealing themselves. More tweaking of the filter setup is showing hints of the filaments though which is positive.

CaK Sun 7th April
Less than ideal conditions but I mamanged a quick grab of the sun in between the clouds!

Calcium Sunshine 6th April
Finally a bit of time, and despite storm Kathleen bringing gales and skies filled with Saharan dust an opportunity to observe. Trying out the custom Cak filter here, an Alluxa 0.14nm double stacked with a CaK PST filter, seems to offer an improvement in terms of a narrower bandpass with more contrast. Hopefully better conditions soon will allow further testing.
