SPX350 F4.53, ATK-16HR, Astrodon Ha5nm OIII 3nm and RGB for stars.
Ha-2hrs in 10min subs.
O3-8hrs in 15min subs.
RGB-10x2min subs each for stars.
Taken throughout second half of July this conspicuous object with 2 bright patches either side of a bright 5th mag star with faint outer filamentary shells. This object should have a name, bright patch looks like 'safety goggles'?
Others have caught this object in widefield showing filaments well so though it needed a closer view. Had problems with secondary collimation as mirror seemed to move ever so slightly when slewed so now it is tightly set. Looks like a bipolar planetary nebula.
Type O star at 40x Sun's mass and very hot throws off outer most shells of gas periodically like Bubble Nebula NGC7635 in Cassiopeia, it will live to only 6mill years and is past halfway. Object is 4,200lyrs away and 4.2 lyrs across.
The first one looks like it was taken through the Canada France Hawaii telescope or something there's detail in details - love the little turquoise speaker cone just left of the star.
Really makes me want to take the AG12 to better skies/seeing now
Lovely work John, I like the variety and quality of your work, something new every time.
It's amazing the subjects there that just need a different eye to reveal the unexpected. Keep it up !!
OMG! John,fantastic work! wow,the bubbles....I think this is amongst the most exciting work I've seen this year! congrats on an awesome display of images.
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?
Greg.
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.
.....WOW?
there's detail in details - love the little turquoise speaker cone just left of the star.
