The Eta Carinae Nebula (NCC 3372) in Carina - Mark III (higher resolution linked)

[Paul Haese]

Nice image H. maybe just a little pink for my liking but each to their own. a larger image will show the image better.

[Octane (Humayun)]

Rich,

Thanks, so much, mate.

I can see a reprocess in my future. I had an earlier incarnation that I did, which I spent barely ten minutes on in Photoshop, and it has a lot more depth and colour in it. I will try and emulate that result. It has a 3-dimensional feel to it, too.

Looks really nice, can see the Gem cluster and Mistral neb which look outstanding...... but, could you publish a larger image H ??
This present one with the link I'm really only seeing 2/3 of it on my monitor..
be good to swim around in it some.
Go on, you've got the real estate, lets really see it

It's great your under way old chap
Talk about patience

All the best
Rich

Alan,

Thanks, mate.

Marcus,

Woohoo, thanks! It's a great club to be part of, too!

I agree I can tease more out, it's due for a reprocess already (once my right shoulder stops hurting, haha!)

I didn't blend any hydrogen alpha into the red channel. I did an RGB combine in MaxIm DL. I might actually try just merging individual RGB frames in Photoshop. That way, I can experiment with blending hydrogen alpha into the red channel. At the end of the day, I don't care for scientific accuracy; I'm an artist -- if the image has depth and is aesthetically pleasing, without being /too/ funky, then, I'm happy.

Thank you, sir.

You definitely need to display a higher res version though ... full res would be nice! I want to see PIXELS!

The colour looks spot on to me but I'm suspecting you can tease out some more depth of neb from your HA (?) Did you blend some HA into your RED channel?

Cheers, Marcus

Greg,

Thanks so much for the advice (and your message, too; will reply to you soon).

Agree with you, it can be saturated more (as per my reply above to Rich).

As for how I combined: I combined RGB in MaxIm DL and stretched. I stretched the luminance and hydrogen alpha frames, as well. Then, saved as TIFFs and sent to Photoshop. In Photoshop, I processed all three data sets separately, with various curves iterations, and vibrance/saturation for the RGB set. So, my final image had three layers. One RGB, one luminance (set to luminosity) and one hydrogen alpha layer set to luminosity at 64% opacity. This seemed to strike the best balance between saturation and overwhelming the field with stars.

It is a learning process, and, one I'm not scared of embracing. I've got a fairly sound understanding of Photoshop (been using it since 1997!) and I'm sure it won't take me long to get to grips with it all.

Thanks, again, mate!

You have gotten your stars to look nice. But as Marcus pointed out there could be more of the Ha neb teased out and perhaps a bit more saturation in the neb colours (at least to my taste which is subjective of course). That is the cost of Ha as Luminance. It tends to wash things out and it also tends to make the Ha areas more pinkish again that is fine but is a taste thing also. There are a few schools of thought about how to blend in Ha. I have tended to take some from both plus a bit of my own. I also think the approach varies a bit from image to image. I am happy to PM you some approaches. My current view is Ha is a beast that needs to be reined in otherwise it dominates the image too much. Yours is nicely controlled from that viewpoint.

How did you combine your LRGB? That can make a fairly big difference to the image as well depending on how it is done.

Fabulous first light.

Greg.

Jeanette,

Are you describing yourself there?

Thanks!

Rob,

Thanks! I'm glad I got it all working, too. Just waiting on my RoboFocus to be repaired/replace and then everything will be automated.

It is such a joy to work with data that is clean and free of perceptible noise. Although, this could just mean I'm not stretching aggressively enough. Time will tell in future reprocess jobs.

Cheers!

Seriously though, that's just candy to the eye - pretty pretty please can we see a higher res?

Edit: Oops - you did of course link to a bit higher res - just drinking it in now.....

Doug,

Nice choice of words, lol.

Thanks so much, mate! This should have happened at Border Stargaze last year (on a different object, perhaps), but, anyway, the ball's rolling now!

Good stuff Mate. Keep it up.

Trevor,

Thanks!

Martin,

Thanking you!

Dr. Paul,

Thanks, heaps!

Have taken your advice on board and will be applied in a future reprocess.

Cheers.

David,

Thanks, mate. Glad you liked it.

Thanks! Go on, you know you want to get a monochrome CCD. Despite the fact that it's been six months in between drinks for you (read your other post). I think I'd be happy if I'm able to produce a coloured image once every two months. I'm already thinking of doing hydrogen alpha mosaics for the moonlit periods.

I like the higher res version, but an even higher one would be worth it for this fine image.

Cheers

Troy,

Thanks, heaps, bro. I think it came out alright.

Fred,

I still remember what you said to me at IISAC 2009 -- that I was ready for a monochrome system and that I'd find it easy to make images. It's taken a while, but, I'm there now. Here's to lots of clear skies this year and a few nice images.

Ken,

Wow, thank you so much, sir!

Darren,

I can't begin to tell you how happy I was when everything came together. When the RGB combine appeared in MaxIm DL, it was like a revelation, haha! Thanks!

Alex,

Thanks!

So glad you like the colour and framing -- you just have to ask Frank how much deliberation I put into the initial framing. The goal was to cover NGC 3293 as well as the veils on the right-hand side, and have it all set in a way which was aesthetically pleasing. Once the framing was done, PinPoint LE did the rest in between focusing runs and changing filters and shooting over the various nights.

Now for some crops and a full res version

Mark,

Thank you, mate, I am very happy!

Paul,

Thanks! That would be the hydrogen alpha washing through, I suspect. I am ready for a reprocess soon.

[Octane (Humayun)]

You guys are such a pain! By popular demand, here's a high resolution version.

50% resolution.

Hope you like it.

[spearo (Frank)]

H,
The high res wont all fit on my screen so lower res please (I'm only kidding everyone!).

I've just come back from a long weekend and just read this post with the dedication.

Lisa says thank you, how lovely (she was very impressed)
I say where's my 20% !!!
Ok for you 15% but final offer!
:]
kidding
pleasure always
great result on the image, I expected no less.
well done mate
frank

Thanks H

[richardo (Rich)]

Now that's what I'm Talking about

Been swimming around the hi res version and yes, very B<**#dy nice I must say.

Once again... great first light H!

All the best
Rich

[SkyViking (Rolf)]

Aah thanks H, what a glorious view at the higher resolution! Incredible for a first light really. I think this is one of the finer Eta Carinae images I have seen. Delightfully understated while full of details and, as you know, perfectly framed Looking forward to 2nd light, whatever it might be!

[strongmanmike (Michael)]

Humi.....

Well, if you are going to image the boring'ol Eta Carina Nebula it had better be a good one, if you are going to post a first light it is good if it is a cracker image...and mate you have done both here

Superb result, beautifully balanced and believable image. Your DSLR images were amongst the best now you can see this same quality but better with the mono CCD, top stuff.

It may have taken a year but it was worth the wait.

Thanks for the view t'was a real pleasure...I don't use this imoticon very often and it must be a cracker and reeeeeeeeeeaallly warranted so here you go...



Mike

PS. The 50% image size should be your standard now, the first image size you posted was just a tease.

[TrevorW]

Thanks H for the bigger one shows up the detail really well

[gregbradley]

The larger version is fabulous. Great star colours and nice rich nebula colours. You got a great balance there.

Greg.

[atalas]

Ok H,It's a nice shot, well composed,good color, but over 10 hrs on eta.....It's time to tie your hair back,get out of safe mode mate and really show what you can do with this shot! a bit harsh? not for someone with your talent !!

[multiweb (Marc)]

Real nice first light. Loved the higher res version.

[danielsun]

Wow H, that is awesome! Truly stunning work mate!


Cheers Daniel.

[Screwdriverone (Chris)]

Hi H,

Oh no! That image just jumped onto my desktop! How did that happen?????

Absolute Zero Cool image mate, -273 degrees below!!!

Might have to start calling you Zero Degrees Kelvin....

Or perhaps just Kelvin for short.

Divine work

Cheers

Chris

[Octane (Humayun)]

Frank,

Haha!

OK, for you, 25%

Cheers, mate.

Rolf,

You're far too kind. Thank you! I just need time to reprocess it; I know I can cultivate more out of it.

Mike,

Yikes, high praise, indeed.

And, yeah, I'll present 50% resolution images from now on as a matter of course. Not for my terrestrial/landscape stuff, though. People can buy that if they want to see detail. : P

Louie,

I know, I know. I can do better. I should perhaps have waited until it was a corker. But, that'll be round 2!

I appreciate the constructive criticism. Glad to know you think I can do better.
