It was an interesting morning with cold temps again (18F/-7.8C) but the winds were low so not too bad.  Unfortunately in these temps the BF tends to go off band over time even when using the heating block for the BF.  I started an animation of the Eastern Limb after the full disk image to catch the limb and the long filament on the eastern hemisphere.  As time went on the contrast faded (or so I thought) so I stopped the animation after 40 minutes and did one with just the proms.  The 2nd animation covered 1 hr 36min but after processing the first in PS and Pixinsight I was able to get some decent contrast so I wish I had stuck with the surface features as well as there was wonderful motion in the filaprom on the East Limb.  But, some nice movement in the prom only animation  as well, but seeing had degraded a bit.  I imaged between 14:36 - 16:56 UTC.  Seeing went downhill during the prom only but kept it for the floating plasma groups and activity, so it's a bit soft.  Glad I was able to come inside to warm up as the temps were in the teens (F) most of the time!  I was surprised by decent seeing just as the sun cleared my neighbors roof, I would have thought the atmosphere just above the roof would be roiling but it was much steadier than when it climbed higher from the roof!  Go figure!

Forgot to mention that the flare at AR3917 in the first animation was a C5.9 Class flare.

Nice shots Warren! 

 

It's weird looking at that view thinking nearly -10oF and no snow on the ground! (Here in W. Can., if its that cold, we have 90%+ chance of snow stuck on the ground!) 

 

Looks like a VERY clear sky though, despite having the sun "skate" near the distant house roofs! :)

 

I guess your Quark has a wider T range than advertised, so lucky you!

 

Cheers, stay warm out there!

Very Nice Flare capture Warren! Thanks for these! Much less people posting Halpha captures these days. And I can understand why!

Thanks Darren!  No Quark, this is a double stack Lunt 60mm, both etalons are tilt tuned.

Thanks Steve!  Yep, low temps and low elevation do present a challenge!
