Description

Here's my attempt on the Bubble Nebula. These short nights without astronomical darkness are terrible but I take what I get ;) I am not so lucky with my OIII subs somehow, the detail in those are very faint and I always seem to end up to overlay Ha as Luminance.

I chose a quite aggressive crop as final because I was impressed about the fine H-alpha details surrounding the bubble, have a look at the full resolution. Also I added a full field view.

Hope you like it. Let me know what you think!

Edit: Changed from crop to full view again. It is definitely worth a look in full resolution ;)

Replaced the big star with the RGB version to get rid of that nasty halo

Repaired stars and reduced blue in the core a bit

I thought the image was a bit pale and the bg too dark...
