NGC1948 Neb and others in NB 44hrs

[Bassnut (Fred)]

Hi Guys

NGC1948,1945,1946,N49 (and others) Nebulae in NB in the LMC. Click Here for big.

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 off 3nm Ha subs 40min each bin1. 31hrs . 11 off OIII 3nm subs 40min ea bin2 7.3hrs. 9 off SII 3nm subs 40min subs bin2 6hrs. Mapped Ha.SII.Ha.OIII. LRGB.

This view was fairly dim hence the hours and still its not that sharp and a bit noisy OIII is quite strong. I cant find much detail on the various objects, the bubble I have already posted appears to be NGC1945 or NGC1946 but no pictures of these on Google to compare. I also have previously posted a really bad version of N49. The only other pic I can find is Hubble, and its amazing natch. N49 is very bright and blown to bits in this view.

Looks good to me Fred. Certainly very colorful.

Wow 40 min subs, that's awesome Fred. Looks good to me mate, lots of details, and very arty looking colour. Top stuff.

Another interesting and challenging image, Fred!

Not sure if it's the original image or Smugmug, but it doesn't have an ICC Profile?

Cheers,
Rick.

Cool image Fred. Bottom right object looks like a bizarre brain. What is that?

Thanks Rex. The OTA is only 10" and with 3nm filters 40mins is my standard now.

Ive googled ICC and I still dont understand. Have I done something wrong?, Wrong colour space?. The Jpeg is whatever PS uses as default. I dont think smugmug messes with it and I dont include a "profile" in the pic data that I know of.

Thats N49. Have a look at this and weep .http://apod.nasa.gov/apod/ap040306.html

It's a good idea to convert images intended for web display to a lowest common denominator colour space like sRGB and include an ICC colour profile. That means you'll get something reasonable on dumb systems that don't do colour management (and typically approximate sRGB) and also that colour managed systems will display something that looks close to your original image.

I'm not sure what PS does by default. I'd guess it uses a wide gamut colour space like AdobeRGB?

Cheers,
Rick.

Ta, but you know Hubble doesn't count..

Ah! The wide field in colour - nice!

Actually went back and had a look at your close in view and man...looks good

Interesting field Fred. What made you choose this area? Was there something that really caught your eye? The region in the top right has caught my eye. At full res there is a lot of knots of gas.

Great looking photo Fred.

Amazing detail...looks like a robot holding up its fist!

Thanks Guys. I was imaging n49 and noticed some other stuff in the full frame not mentioned much. Might have a go at more in there seperately it doesn't look too crappy zoomed in

Gorgeous, love the colours. And is that an IIS record, 40 minute subs?!!
