March 27, 2017: Ca-K and WL disks (and WL detail) with some new activity

[michael.h.f.wilkinson]

Managed to grab quite some data over lunch, with glorious sunshine, and pretty good seeing. I first had a look in WL and spotted the new AR that popped up over the weekend. I totally missed the little spot on the western half of the disk. I only spotted that when imaging in Ca-K. Later during processing I spotted yet another AR close to the eastern limb, with a sprinkling of small spots or pores amidst some faculae. A lot more going on than last week.

WL detail, grey scale. There is a bit of a dust bunny to the left of the AR, but otherwise very pleased with the detail

I have a set of 6 Ca-K panes taken with the 2x TeleXtender stacking at the moment. Hopefully they will stitch into a mosaic. I might also get a set of H-alpha images this afternoon from home (summer time can be handy)

Very nice Michael. I am really quite fond of the way that CaK images look. 

I'm starting to prefer them to Ha.

That spot group  is developing  very well, it might have me rushing  for my white light set up.
