Description

Normally I am a night person. However, the upcoming Mercury transit got me and I built a solar filter for my telescope. I also got a QHY-CCD 5L-IIc, but this here was the first test with my old mirrorless camera. I chose the camera filter foil which maybe was the wrong choice. My camera has an exposure of only 1/4000s and I got rolling shutter effects in single photos.

This here was made with a video, much better than the photos.

Please be nice, this is my first daytime astro photo! ;)

Version A: 300 frames of a video stacked

Version B: 5 photos aligned in PIPP and stacked in PS, with subsequent false coloring. This image badly shows the rolling shutter problem: the sun is much darker in the top. No idea how to correct that..

Version C: I tried some flattening in Fitswork and some gradients in LR. Not it looks better.

Version D: I tried to get more surface features, as far as that is possible without any filters..

Version E: Minor corrections to get a more natural outer region.
