Lots of minor activity in AR 2661 (animations)

[GreatAttractor]

I've had a fruitful weekend: good seeing (for 90 mm aperture, that is), crystal clear skies on Friday, and equally good seeing on Saturday with 1/3 cloud cover miraculously sweeping sideways from my location since morning to 4 pm. Too bad I caught only one stronger C-class flare in AR 2661 in all those hours.

Everything captured with a 90 mm refractor with Lunt 50 etalon, PGR Chameleon 3 mono (ICX445), processed with Stackistry and ImPPG, showing AR 2661.

Overview shot of AR 2661 on Friday morning:

Friday, 30-s intervals, 0:53 h and 1:06 h. Lots of small-scale activity, too bad it wasn't exactly on the limb as on Thursday; the spikes and surges would look even better (as in http://astrob.in/262196/B/):

Saturday, 30-s intervals, 2:15 h total. A class C2.1 flare peaked at 9:57 UTC (preceded by a few smaller events around):

The flare maximum:

 

And the whole material from Saturday on fast forward (5-minute intervals, 4:45 h total), showing the changing aspect as the Sun rotates:

Have you got any pictures of or links to information on your 90mm refractor / Lunt 50 Etalon setup?

I have Lunt 50 and LS50C Double stack but there doesn't seem to be any adapter available to mount the LS50C on any refractor (although the LS50FHa does have adapters available).

Unreal images and animations!

[David Smith]

Some awesome images. Typical, first AR in some time and the forecast is for a week of rain and other forms of meteorological misery

It's a “mod” which increases the aperture (and resolution) at the cost of reduced sweet-spot size (i.e. whole disk cannot be viewed in Hα). Details:
