NGC2018 Nebula and N206 Supernova Remnant

[Bassnut]

Hi Guys

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.

Great work Fred :thumbsup: not many good shots of this out there mate, an intriguing bit of gas....

For comparison, Here (https://angelrls.files.wordpress.com/2016/11/ngc2018_bo3ha_lamina.jpg) is just a few minutes of exposure framing a small section of your image, taken through the 3.9m AAT at prime focus :thumbsup:.

Nice

Mike

Thanks Mike. Gee thats interesting, 15mins on the AAT!. The colour mix is so different, would you prefer the AAT pallete?.

[strongmanmike]

Nah, yours looks fine :)...be good to see the full 2deg on the AAT :eyepop:

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 :P

You've got some pretty nice detail in there :thumbsup:

[RickS]

Very cool, Fred. Looks like the evil, stunted twin of the Running Chicken :)

[Placidus]

Excellent, Fred !!!

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.

Once again, beautiful work.

Gorgeous intense detail there Fred.

[Shiraz]

gosh that is good. very deep image of another of the fascinating and very strange looking structures in that region.

edit: just did a quick search to see what the structure is - if any interest, summarised nicely here http://www.aanda.org/articles/aa/full_html/2012/11/aa19532-12/aa19532-12.html

Great shot Fred. Nice and deep too. Excellent processing.

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.



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



Thanks Simon



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.

[Placidus]

Thanks for the Don Goldman annotation, Fred. Seems we guessed correctly about which bit was N206. :)

[Andy01]

Wow, looks like NGC 1929/37 puffed up after a few beers and baked beans!

Nice one Fred - havn't seen that guy before - a fascinating object well captured and processed, bravo! :thumbsup:

[graham.hobart]

Wow!
Looks a psychedelic bear diving towards you.
Impressive.

Gday Fred


So remove the stars!!! ( Like you normally do:lol:)

Andrew

[Bassnut]

Thanks Guys. Removing stars is a righteous pursuit to be sure, but its hard work and a getting a bit passé these days unforch.
