Thanks for the response I appreciate it. I discovered this object in Marco's widefield APOD image with a faint halo around the bright bubble.

I like the 2nd one the best. Your optics are sharp as bro.
I am amazed at the level of detail you have picked up.
Do you think the 3nm O111 was a big part of that?

Yes Greg the O3 has a transmission of 97%+ (at F8) which for 3nm is astonishing and it gives a noise free image with less noise than the Ha5nm filter, 3nm is the way to go for NB.
Attached Ha5nm and OIII 3nm raw images 10/15min subs.
The Orion Optics SPX has 1/10.5 wavefront primary but seldom works at that level with avg seeing but is great for planetary -a very flexible scope.
Discovering all these new objects in my new home of Australia is great fun and never ending.
