Full disk H-alpha animations on 26th July 2021

Post by cmas »

On 26th there was not that much going on with protuberances, but the chromosphere activity looks pretty good and a lot is happening all over the "surface".

I have an issue as my Alt Az mount causes image rotation which is not fun when it comes to image processing. So even in 1 hour animation (as these are) the image sensor rotates a lot and I did not have space to crop these so that the solar disk would be visible all the time and no rotation of frames would be seen. As an afterthought I should have probably made a larger blackish frame to put "under" other layers so that there would have been at least a black "solid" frame under all others. Unfortunately I don't have time to do it now and I don't want to come back to these on a later time as my vacation is pretty much done for this summer. So, sorry for any frame rotation related vomiting - my bad and I promise to make these in some different way next time. My lame excuse is that when I was building these, I was checking the animations on a black background and they looked ok, but now I see that on lighter backgrounds they look pretty bad.

Edit: Well, could not live with myself so I added black frame in the background. Quick and dirty solution.

First a couple stacked still images in color and in black & white. Then a 43 fps BW animation from which one can see the chromosphere movements easier and then 30 fps animations in BW and in color.

These are excellent :) you made me laugh when you said " frame rotation related vomiting" that's what my hubby used to say when I did animations with the PST :)

Some fabulous movement here, the upper filament is sucking in material from the AR to the right. It almost looks like a marching caterpillar sucking in the food. I like it a lot!!

Well, it seems that the we need a name for this syndrome. Thus, I suggest FRRV (Frame Rotation Releated Vomiting) and it's known to only alt-az imagers :bow2
