13 Hours of NGC6188 from burbs


NGC 6188 is an emission nebula located about 4000 light years away in the constellation Ara. This image is presented in typical Hubble color Pallet.

Image Data: 20 x 12 min Ha, OIII and SII Bin 1 x 1 (approx 13 hours)
Camera: SBIG STF-8300 with FW-8
Mount: Paramount MX
Scope: Takahashi FSQ106 at F5
Processing: Image Processed with CCDStack 2, Photoshop CS 5.5.
Location: Inner suburbs of Melbourne Australia
Date: Taken on several nights between 1 May and June 10th 2012


Big learning curve processing this one and took me about 4 redo attempts to get it to where I was ready to post as I was certain there was a decent image in all this data. Afer first 2 attempts I went back and grabbed more SII and OIII data which was the turning point.



Hope you like it.

Great image Chris.

I think narrowband suits this object better than HaLRGB.

Thanks. Yes it was about 4.5 to 5 hours of OIII and SII and about 3.5 Ha from memory.

Thanks you. You are too kind. What help is seeing images like Martin Pughs which gives you a sense that there is so much more in your data than you realise. My first 2 attempts at processing this were just rubbish.

Sure does Greg. I like how different it can look depending on how you treat colors.

Thank you. My Skills I am sad to say are only about half of it. Being lucky enough to have nice equipment is a big part of it.

Some good reading on the subject of Narrowband processing also helps.

I found these articles very usefull when processing this image:

Superb, Chris.

Although, I'm going to be critical -- your composition would have worked better had you caught the planetary in it as well. That is, a horizontal composition, twisted vertically, in post.

Still, it is a beautiful piece of work, as is. Print, frame, and hang.

STF 8300? Looks like a winner. Nice one! I'd put it on the new ASA H8 f/2.8.

Agreed completely

I did not know that planetary on right was there. But I had gathered too much data to change composition on first night. Next time i woudl either rotate or shift whole thing to left.

Very cool color blend. Little grainy in the core though between Oiii and Sii stars. Heaps of details too.
