Animation of AR12671 in continuum 22 August 2017

Hi all,

Here is my second attempt of making granulation animation.
10 SER files were made during 11 minutes.
Scope: TAL-250K, Barlow 2x.
Filters: Baader Astrosolar Photo + Baader Solar Continuum + Baader UV-IR block.
500 frames of 4000 stacked in AS!3, LR deconvolution in Astra Image, video assembly in VirtualDub.
There were some very thin clouds, brightness changed, so frames brightness changes as well. I tried deflicker plugin for VD, but with small success...

That was a good attempt, Dmitry. I can see the granulations change within that time duration.

Franco, Alfred, thank you for comments.
In fact, I am really surprised how quickly granulation changes in time. One should be really careful selecting maximum duration of the video to be taken without noticeable changes in details. It seems that at this scale 1 minute is the reasonable limit. Luckily, there is a possibility in AS!3 to select manually short time period of best seeing in longer video when there are several of them.
