NGC6337 Cheerio Neb-close up

[Bassnut]

Hi Guys

NGC6337 Cheerio Nebula in colour mapped narrowband.
Ha:OIII:SII Ha 2rs:OIII and SII 1 hr: all 900sec subs at bin 1, mapped as RGB.

This one is really small and dim. Image capture was a big mistake, I spent too much time with 3nm Ha hoping to use it as lum, its mostly OIII.

Proccessing planetary nebs is a random experience, in this case Ha as lum was a shocker, hence the RGB only processing, they are all quite different, and its hard to know which pallet/processing to use with so few examples on the web, and relative signal strength is only obvious once capture is done.

AO was working at 4hz, but high wind shows with slightly dodgy guiding.

Its a bit technicolour, but since I cant get close to Hubble, its hopeless trying to guess whats best, so I just went for pretty ;).

Oh for 20", 16meg/95%QE, dark skies and 5m FL :P.

Very interesting shot Fred. You can see the violence in its creation there.

You can also try using O111 as luminance if that is where the detail is.

Top image Fred, I remember seeing an image of this in a magazine and it looked very similar to yours.

Thanks for the view.

[Bassnut]

I tried OIII as Lum, it just got brighter, its nearly all OIII. The OIII filter is only 6nm unforch, so nothing gained as Lum in his case detail wise.



Thanks Lester. It seems to be whats achieavable without more apature/longer FL/faster AO.

Colourful Fred and interesting

[strongmanmike]

Well...that's pretty excelllent Fred :thumbsup:

Love it

I think you should keep with these PN's, perfect your technique and you may have found your niche talent...(apart from Starless Lagoons and rediculously long exposures of tiny areas of the sky :lol:).

I think it's a great capture of such an insey wincey PN.

[Bassnut]

Thanks Trevor, Mike, Dave

What im missing of course, is "resolution", which you Mike, have in spades :P :prey2:

[desler]

Really eyecatching image there Fred, very nicely done!

Loooooking gooooood !!!!!!!!!
I did this one with the ED80 and the 40D and it was very tiny :(

[Octane]

Fred,

That is insane! I am a great admirer of your penchant for tiny objects of late. Showing us things we don't normally see.

How far away is this puppy, anyway? To imagine the forces involved to cause this. Dang!

Crikey!
Well nabbed!

[wasyoungonce]

Just beautiful!:thumbsup:

But 5m FL...insane...I say!:eyepop:

[CoolhandJo]

Challenges of these obscure objects seems difficult. Glad someone is taking them on! :)

[jase]

Yeah, not sure Fred. If the object was strong in OIII, I personally wouldn't have picked the CFHT palette to portray the image. SHO or HHO combination may have shown more detail. Anyway, I like it. Its bold, edgy and a defining statement.

[Bassnut]

Thanks Darren, Martin, H, JJJ, Brendan, Dr Paul n Jase.

Brendan, your Jupiter neb was pretty damb fine with a non modded 450D, now THATS hard ;-).

H , I cant find how far away it is, buts its rare apparently, a fast rotating binary.

Jase, I played with SHO, but it it didnt look so "frantic" or "hot".

Mmm, fruit loops in space ;) Nice work

[trent_julie]

I really like it Fred,
What size in arc seconds etc is this little neb?

[Bassnut]

Thanks Adam, Trent

Its 48 arc/secs in diameter and mag 14.

[richardo]

Great going Fred once again!
Certainly enjoy seeing these little PN's.
Ahhh, I can remember imaging at F9/ 1800 fl with some ridiculous image scale and always swore at the mount for not tracking and guiding as I thought it should....

Man, the AO unit is surely worth its weight with close ups like the ones your pumping out.

Keep up the great work!

That's narrow minded imaging! :lol: :poke: ;) Top work as usual Fred :thumbsup:
