h-alpha, January 16th, 2021

Post by LTHB » Sat Jan 16, 2021 7:20 pm

For a few minutes this afternoon the cloud cover was thinning enough to capture a couple of videos, however through passing clouds. After all stacking yielded two images that were a bit unevenly illuminated, but good enough to process further, a disk and a close-up of the southern part.

I also used these videos to try out PlanetarySystemStacker, a new stacking software that seems quite good to me, probably at least on a par with Autostakkert: https://github.com/Rolf-Hempel/PlanetarySystemStacker (There is also a thread on CN about it.)
After this quick test I think it may even give a bit better results for parts of the solar surface with low contrast (e.g. the rim of the disk), but I've only used it for a few images so far. I'll try it out some more as soon as the weather allows.

Kind regards,

Frank

Nice southern portion, Frank. Shows the magnetically disturbed region and filaments very well.

Fantastic shots and great to hear about the new stacking software, it is always good to have an alternative when one fails :)

Frank:
It looks we are all fighting clouds, hope to get some gaps today, though I don´t think so it is clouded all over.
You got some nice images anyway.
Best wishes,
Eric.

Thanks, folks!

I've played a little more with PlanetarySystemStacker in the meantime and I am quite impressed. It stacks quite good, and it also has sharpening tools similar to Registax, but more user-friendly. The only feature I am missing is LR deconvolution.
