The Sun 3rd Apr 2016 Ca-K

[David Smith]

Long session dodging clouds today. White lights still to process.

6 Pane FD @ 1000mm FL.

Close-up on the AR @ 2000mm FL. Didn't think this would work as the seeing had fallen off quite badly by the time I shot this vid.

And the proms including "the wrench"

great set Dave, cracking detail as allways. thanks  charl.

[Pete Presland]

I shouldn't moan after yesterdays blus skies, but I would like to have seen the wrench!  Very well captured again David.

Cracking images, I captured the larger prom, didn't see the "wrench"

 

i have a question, you have a horizontal line , a boundary between light and dark. I have similar (but much more pronounced), do you know what the cause is?

cheers

Lovely Cak images, too much cloud here today.

Thanks guys, very lucky to have had a few days this week whilst off work. Back to work tomorrow unfortunately, I could get used to this full-time solar astronomer lark

To be honest Ant, I do not know what the cause is. I only see this bright bar when I ramp up the gain & exposure for capturing the faint prominences. I kind of assumed I was reaching the limit of what the camera was capable of. I try to minimize it's effect during processing but it is hard to reduce this without impacting the image itself.

Very nice set of Ca-K images. Well worth the cloud dodging.
