Description

While I am still waiting for the snow to melt and air to warm bit more here in Finland I remembered that I have this flyby somewhere but not as an animation here in Astrobin. So here goes. You know, h-alpha is too easy nowadays so why not to combine it with bird watching, right ;) This is almost 100 MB gif animation so it may load for a while.

Animation is deconvoluted and colored but unstacked with a bird flyby during one of the imaging sessions in July 2021. Frames have been processed with ImPPG and animation built in Photoshop. 164 fps with ASI174mm, 1.1 ms exposure and gain 120 (30 %).

In 2021 I was imaging full disks with the Quark so the etalon was working around f/24 which is not optimal and the sampling was not optimal also. But I got some full disk animations which was fun.

Unfortunately the animation is not very smooth even at 60 fps. MP4 format is, but it does not work here. That version you can see from Flickr: https://www.flickr.com/photos/130947324@N08/51325245972/
