Description

Boy, what a challenge!

;-)

Needed a couple of days to process that to my personal taste - not using layers in photoshop to just combine short and long exposures (which you always can see clearly) but to combine true HDR data in Pixinsight only for a natural, smooth transition between the very bright core and the faint surrounding nebula parts. So I'm talking about one (1) single linear image that got processed in PI from the start to the end.

Be sure to look at the details in the tiny center part of the nebula!
