Original (dont know where that one went after uploading the 1st revision)
The night was nowcasted more promising than it realized later on. Lots of high thin rolling clouds. Not the best conditions to create a two pane mosaic with both elements having a high match in properties. The second panel was due to neighboring obstacles limited in integration time and only has one hour. The first one with 2.2 hrs is of course less in noise levels. And due to the clouds brightness was very different. To that effect an ~50% illuminated Moon which was quite close to the targeted objects also contributed to differences in brightness.
1. Revision
Second run of the now more balanced and equalled single frames wrt historgram. Merged them via ICE and did not apply the automatic process (not sure that contributed to the difference) and now had a much more seamless result.
