Coona Corona........improved "glob" version

Hello,

Another photo from my last trip to Coonabarabran in April, Corona Australis.

35 sub frames consisting of a combination of 20 minute, 10 minute, 5 minute and 2 minute exposures. Total exposure was 270 minutes.

There is a slight cropping of the left and right edges to help composition.

"Correct" colour was again the most difficult part of this exercise for me.

The photo is here http://smu.gs/12KG2H6 (..improved "Glob" version..)

What do you think?

Thanks for looking.


Ross.

Nice colours and detail, Ross. The glob looks a little strange?

I think it looks fantastic. Beautiful colours and very smooth. Well done.

Really nice Like 2 eyes staring at you. Like Rick said too, the glob looks too round or something, doesn't worry me though. Awesome image!

Great colour Ross, and I really like the field of view. I did this several years ago and I would need two panels to get your field of view. I concur with Rick about the globular. Something odd with that, but the rest looks great.

Man you doing some nice work Ross!

Don't know about you, but I find this a difficult beasty to get right. Especially that globular!
It seems me you just about need to cut the globular out while processing the nebula then paste it back in.

Cheers,

Justin.

Beautiful work, except agreed masking on glob needs work. The rest appears natural, which is of course easier said than done. Great data.

Glad you like it Rick and thanks for the constructive advice.
I have tried to improve the glob, but my Photoshop skills are at their limit.

Thanks Eric.

Yes it does look like 2 eyes. In fact, it looks like a baboon's head to me!

I have tried fixing the glob.

Very encouraging comments Paul. Thank you.
The 540mm focal length of the telescope gives a nice, wide FOV.

I have tried fixing the glob. I was too busy worrying about the colours to notice anything else.
Trying to blend the 20min, 10min, 5min and 2 min exposures I think has resulted in the glob looking like a ball.

Thank you Justin.

It was a very difficult object to process.

I did exposures at 20, 10, 5 and 2 minutes, but blending everything was a nightmare!
Getting the "correct" colour was very difficult...if only everything was monochrome!
If I can manage another trip to Coonabarabran soon, I'm going to image this object again in widefield.

I have re-posted a version with hopefully an improved glob.

The second version looks better Ross, with the glob looking better. Like I said only minor really compared to the overall look of the image.

Bah! Was just about to post my salvage attempt on this from last night's cloud-affected data. Not going to now
Very nice, the contrast is really well managed, but the glob still looks sorta 'flat' - not sure if you know what I mean.

Nice baboon's head for sure. The Glob looks like it's been cut and pasted using a square frame. Not saying it has but it just looks too regular like it is a bit artificial, added in after.
Otherwise the rest of the image is stunning.
