Description

Not to bore you all to death :-), but here's another step of my large M51 project: The data of the O-III NB filter. The most difficult task today was to maintain an acceptable color balance. The core was also on its way to a burnout. But thanks to PS I managed to find a good compromise (imo).

To be continued... :-)
