NGC2018 Nebula and bonus N206 Supernova Remnant in Narrowband.
Its a bit dim, so not much sharpening possible. Colour pallet is Modified Hubble with Ha as Lum. Ha,SII,Ha,OIII.
A couple of small uncatalogued nebula in there too.
Taken on an RCOS 10" RC Scope at f9, SBIG STXL6303E Camera and PME mount at itelescopes Siding Spring Observatory.
Processed with CCDstack, Star Tools and Photoshop. 47 hrs Total exposure time. Ha 25hrs, 40min subs bin1. OIII 8hrs 40min subs bin2, SII 14hrs 40min subs bin2.
Very sharp, and you've gotten fainter detail than we got with our version. 47 hours is truly impressive.
Do you know which bit is the SNR? There's a big multiply loculated bubble at about 7 or 8 o'clock that looks very like it might be an SNR, and is rich in OIII and SII, but there are lots and lots of other bits in the image that one might guess are older, more disrupted SNR's.
That's really nice Fred! As Mike has graciously pointed out, you're lacking behind the 15m exposure from a 153.5" scope! Shame on you
You've got some pretty nice detail in there
Thanks Colin. Pics like that from big scopes point out features that might be worth trying to highlight.

Cheers Rick. Gaud starting to sound like Mike, I often have a hard time finding those characters.

Once again, beautiful work.

Thanks Mike. Ive attached Don Goldmans annotated version, and A WR, lots going on there.

Cheers Ray. Yes, many odd balls around there, I keep looking for references and theirs always one more. Thats a heavy read, its amazing how much research is done on just one item.

Thanks Greg. Deeper also means messier background unforch, hard to process with so many stars in the background.
