Description

The little Rosette Nebula... The nebula is actually not that small. ;-) But it needs an incredibly high exposure time to make not only the H-alpha areas visible in the nebula itself, but also in its surroundings.

In eight nights I took up the challenge. :-) The result is my personal record for the longest exposure time I have ever made for an object: 30 hours overall! I also used some of this time for pure RGB shots which were mainly processed in the color of the stars. I hope you like it! I'm looking forward to your comments. :-)
