May 14, 2017: Some more Ca-K

[michael.h.f.wilkinson]

Just processed a detail shot of the sun in Ca-K, hoping to pull out more of the bright plage area. Not much extra too be seen, just a higher resolution image without any pores, let alone spots. I also made a larger stack (1600 rather than 400 out of 4000 stacked), to pull out some proms. This was more successful, and there are some faint proms visible in the part inverted shots.

As always, best seen at full resolution

 So cool you can get proms. Outer edge looks great.

Nice sharp set of images.
