Description

Hi guys,

some of you may know that I really have a knack for starless edits. I consider them to represent nebulae in a form that is more highlighting the nebula itself and not provide the distractions to the eye in form of the stars. I know not everybody will agree with this point of view but this is ok :) Maybe you can still find some aesthetic beauty in this image.

This is the last low-altitude target I have shot this year. It rises only to about 21° at my location and that makes it a challenge to gather enough good quality data for me. Nevertheless I am happy with the result now. I have had this data sitting on my hard drive for a long time and you cannot imagine how many failed tries it took to edit this. Obviously this it not something you see but I am sure you can relate with your own work. After many many failed attempts and continuously trying new things in my edit process I came to this result. I hope you enjoy it :)

On thing I really like about the result is all the faint nebulosity in the outskirts of the nebula. An interesting side note to myself was that I did not expect I would need HDR transformation for this image but the central part of the nebula is so insanely bright that I really needed it :o
