Following on from Ralph's "Quiet Sun", I got a few frames before the seeing went completely out the window this morning (easterly winds, playing heck with the seeing, for seemingly ages now).
The filament that was yesterday is moving over the limb, and becoming a nice prom, if that's what you call it?
Gary
Gary,
Good catch!
I didn't realise you were still doing Ha solar....
When a filament moves to the edge of the solar disk and is still visible both on the surface and as a prom, it's a "filaprom"
Thanks team. You know me Ken, always doing Ha solar, mind you, I did just about cook in the sun yesterday, muttered to myself that an umbrella might be needed to shade the computer and operator.
Long hot fine spell, seemingly endless. It will end soon, and then I'll be back to wishing we had some sun.
Look forward to yours Paul, I've got lots to learn.

Don't expect too much Gary; seeing was pretty average today. This was a test with the new laptop to see if drivers etc and processing power are up to spec. Short answer is it downloads without having to use an SSD at 26fps on a 2.8mp frame and processing 6 panels takes 40 minutes tops. Compared to my old laptop which too 12+ hours to just process out the data for photoshop. And; BTW we all have lots to learn, me included.
Nice going Gary. Especially the way prom and filament remain as one unit and colour. Leaves me for dead. There is no way to achieve that with a DMK 51. What camera did you use to gather the data in one shot?
Thanks all. Ralph. Having been in awe of many of yours, praise like that is cherished, thank you. An old humble Flea2. Usually I have the gamma as "low" as I can, to maximize the contrast etc. However occasionally I shoot with it at "about half way across", real scientific I know, and adjust the "exposure" setting to suit. This means there is less contrast on the surface, but limb details are not completely washed out, or overdone either. Tweaking in the processing (CS4) is about all I do.
I usually shoot a disk with one capture for the surface and another for the limb, and combine. This works well, except where the filament or prom is running "away" from the camera, and therefore in both sections. If I combine the two, the filament is black in one section, and light in the other, looks awful and unnatural. By just shooting the one capture with the wishy-washy gamma I seem to be able to get the best of both. Not always though, sometimes it looks like garbage.

Thanks Gary,
I will give it a try if we ever see the sun again. The last image, only the disc is inverted and the Proms are standard shot. I just combined them in CS6 using a layer mask.
