Hi all,
The seeing did not allow for better images, but I think it is worthy to share this animation made yesterday, since various and varying activity on both the surface and the limb are visible simultaneously. Different speed in small and big prominences, but also some activity away from the AR and the spot is visible if someone observes carefully. Hope next time a better seeing will help to have sharper captures.
Lunt130MT, H-alpha, ASI290, 36 frames, 19:20-19:49 (Athens GMT +3 time).
Please give the animation some time to load properly. Hope you find it interesting.
Best wishes,
Alexandros

That's a really great animation, lots of plasma flow around both spot groups and the limb activity is quite spectacular, well done!!

Thanks a lot Mark and Alexandra for your nice words!
@Alexandra: I like very much your additional informative comments regarding visible activity. They help a lot understand new things for me! :-)
Best wishes,
Alexandros

Re: Surface and prom animation of AR12827, 4 June 2021
Interesting animation, Alex.
It seems to me the focus is a bit off? And I bet you can squeeze some more sharpness out of those frames by deconvolution and highpass/unsharp mask

Re: Surface and prom animation of AR12827, 4 June 2021
Thanks a lot Minh for your comment.
It might be either that the seeing was really bad (nothing to do here with your seeing...), or that because of the bad seeing I could not focus very well. So basically it was a seeing problem.
I don't like to push a lot more the ImPPG, because in many photos and especially when I have bad seeing, I see big artificial 'granules' that are added by the software in its effort to sharpen the image. Have you find a way to limit or remove these artifacts created by ImPPG? I suppose that by 'deconvolution' you mean ImPPG. Isn't it?
Best wishes,

I do my sharpening by PixInsight, I am too having problem with weird artifacts generated by ImPPG especially if I am rendering using CPU. Turn the rendering mode to OpenGL (render by GPU) seems to smoothout the artifact a lot. You should try it.

Re: Surface and prom animation of AR12827, 4 June 2021
Thanks a lot Eric!
The best wish I can have. ;-)
I thought Greece's Mediterranean weather would be enough to have many good solar observation days, and seeing would be equally good when I was following MeteoBlue as only indicator. Now I realized that it is not so, and that an average seeing below 2 with minimum below 1 is rather rare...
But perhaps this makes the expectation of good seeing even more exciting! ;-)
And I can still hope that my statistics are still very limited in the last 4 months.
I hope and wish you have much better seeing than me and you keep enjoying astrophotography every time even more.
All the best,
Alexandros
