March 27, 2017: Solar mosaics in H-alpha and Ca-K

[michael.h.f.wilkinson]

Managed to get six 6 Mpixel panes in Ca-K, and 68 little panes in H-alpha today. Stitching worked well enough, to my surprise.

H-alpha, grey scale:

H-alpha, pseudo colour:

H-alpha, part inverted:

H-alpha, part inverted + pseudo colour:

The Ca-K is far from perfect, as some seams are visible (unsurprising with the variable seeing), but I am still pleased with the first Ca-K mosaic of the year. As ever, clicking for full resolution is recommended
