The Sun - 26th Sep 2015

[David Smith]

Bumper day for solar imaging. Woke up at 8 to clear skies, was setup and waiting for the Sun to clear the trees and it's still sunny now! Some 110GB of data accumulated across white light and Ca-K and that doesn't include the DSLR raw frames. I think I am about 75% of the way through with processing now but still have ~50Gb of Ca-K data that I hope will become an animation at some point.

First up then, white light full disks via DSLR

Next up, white via QHY5. This one is a 6 pane full disk mosaic @ 1000mm FL. I believe this is the first time I have managed to get a white light mosaic to work, thanks largely to the large number of spots scattered across the disk I suspect.

Close-up of AR12422 @2000mm FL. Seeing had gone off some by the time I had gotten to shooting this and hence it's a bit noisy.

Then the Ca-K 6 pane FD which is becoming a staple of my imaging sessions.

I have a 20 frame sequence of this AR at this focal length but yet to process that data.

Finally, Ca-K proms, normal and inverted.

I did try to do a full disk surface and proms @ 500mm FL but struggling to do anything with the data at this point. Will persevere!

Thanks for looking and enjoy the sunshine.

Excellent images David, pretty annoying day here, not a cloud in the sky this morning when I had to go out, got back set up as the clouds rolled in, done a couple of vid's through the gaps but could really have done with blue all day to sort a few things.

Lovely set of images David.

Very nice disks, close ups and proms. No sign of the sun here I'm afraid.

Beautiful Calcium-K shots again David.  It makes me lust after one a bit, but as mainly a visual observer it's probably not for me I'm afraid - at my age I probably wouldn't see much visually!

I've attached a snap taken in HAlpha this morning, single frame, Olympus E-M5 with my Lunt 60mm DS.  As I said, certainly a visual observer first and foremost

Another lovely set of images.  The full disc white light is beautifully sharp.  Look forward to seeing the CaK animation

Superb collection, David. Lots going on at the moment

Great set of images. It's always nice to see the comparisons in HA Ca-K and WL

[Pete Presland]

Fantastic captures especially the cak images.
