More EAA with post-processing in Siril

Conditions were similar to the last time: clear skies but so-so transparency. Also it got quite cold and there were gusts of wind, which triggered the neighbour flood light. Again I took mostly pictures of galaxies and ran a script afterwards using Siril to produce the JPG below.

The commands in Siril were:

subsky -rbf -samples=75
autostretch -2.8 0.1
