Description

Imaged under the bright Moon... The l-eNhance tri-band filter is really effective in combination with my ASI294MC but eben then the bright moon killed a lot of contrast :-) However, I tried to rescue some OIII and a first attempt to work with the data did not completely failed. At least it was the first astrophotography chance for me since weeks.

Description: "True Tone" Version of the same data but stacked and drizzled in PixInsight. No HOO composite this time as there is not really enough signal from OIII for a satisfying result.
