Description

This is an animation recorded between 12:04 and 12:52 UTC (or UTC+3 hours in the Finnish time zone). Total of 55 videos taken with 5.3 ms exposures / gain 125 in Firecapture with 20 second capture time and about 32 seconds between captures. Stacked best 200 frames for each of the 55 animation frames. These are taken with a mere alt-az mount so a slight crop was needed to frame the animation nicely due to image rotation during the capture period of about 48 minutes. 

This is my first longer animation with this setup and it seems to work pretty well. I did capture about 389 GB of SER video so I think I could push the total recording time to 1 hour before running out of disk space in my laptop. The scale is around 0.39"/pix or so.

These gif animations are between 65 MB and 87 MB in size so please wait a bit until they are loaded. I wanted to show these at full size so I did not scale them down.
