Hi Greg
Just wondering when you say HaO111 RGB, how is it mapped?
Do you add Ha to the red channel and O3 to the blue?
Had a good surf by the way

You’re sowing some seeds of interest here, I like the ring nebula 2/3 up on the far left, does it have an NGC number?

It looks like a ghost hooning around.

Incredible field - great framing!
The large size is fabulous to noodle around in.

Thanks Russ. It has minimal processing I think that helps the stars unless you remove them and add them back in later.

Yes it's definitely rich. $$$
I'd really love to see a tight shot of the bubble type feature on the bottom left of your image on its own. I looked on Stellarium and found it, but there is no catalogue number that I can find, just that it is near HIP 26995, if i've got the right bubble that is. If you are looking for something new to image it might make a killer image set on its own against a dark background. Maybe you can see it better in your higher res data as to whether it's worth chasing that bubble feature on its own at higher focal length or cropping ... or not .
