Deep Rosette from suburbs of Melbourne

[cventer]

Been working on this now for many weeks. I Can't seem to ever find enough time to process images so enough is enough. No point sitting on my PC and not sharing.

I present to you a deep Rosette image in narrowband taken from suburbs of melbourne.

I posted some crops as well that show some of the interesting detail.

It's about 15 - 20 hours of data in Ha, OIII and SII. I will get exact figures and update.

Large version here (http://www.dslrfocus.com/gallery/NGC2237Narrowband.html): I f you have a large enough monitor there is a link to full frame as well. You need to stand back a few feet to truly appreciate all that goes on in this beauty

Taken with Orion Optics AG10 and SBIG STF-8300 on Paramount MX

Great stuff, Chris. You must be very pleased with that. You've obviously got the AG10 well sorted out.

Cheers,
Rick.

Great work Chris. Incredible detail.

Greg.

[ourkind]

Excellent detail and I really like to tones too! Well done thanks for sharing :thumbsup:

[Larryp]

Very well done, Chris!

[Rigel003]

Beautiful job, Chris. Lots of great detail and the colour balance is very attractive. This is such a big object it's crying out for a larger sensor with your setup.Did you replace the stars with RGB or just desaturate them?

[Ross G]

Great looking photo Chris.

Amazing detail.

Ross.

Thanks

I have my 16803 sensor so thats going on the scope shortly.

I did not desaturate , but used a technique called tonemapping to generate the color pallete. The stars then come through from the luminance channel only, so you dont need to desaturate. I tried using stars from color channel but the magenta rings you get with narroband detract from the image.

Very nice color palette. Beautiful saturation. :thumbsup:

[cventer]

Thanks. Allways tough to know how far to push it.



Thanks Ross. I grabbed a lot of OIII and SII data on this which is why the blues and reds are quite strong.





Thanks for looking.



Rick. I guess I do. I did not take much sorting to be honest. I just have not had time to process images. I have about 8 images worth of data backed up that I need to get to.

Nice work Chris!

The AG10 looks more than up to the task.

Cheers

terrific!

your site reminded me what a shame it is that DSLR Focus was never updated :(

[marc4darkskies]

Excellent Chris! I like it a lot :thumbsup: Good on you for posting full res too!

Can't help but be reminded of a pair of purple corduroy pants (with matching wide purple tie) I had in the 70's though. ;):P

Some additional graininess visible in the full res in patches - sharpening artefacts?

Cheers, Marcus

[cventer]

Thanks Marcus.

Not likely to be sharpening artifacts as I mask all sharpening activity to high signal to noise areas only. Likely to be just lack of signal and not enough smoothing. I took it very easy on the smoothing and probably could have pushed smoothing more in lower signal to noise areas than I did.

I will have another look and may post an update. Thanks for to comments

Thanks Niko

Re dslrfocus, yes was a shame. I was the first to bring this dslr control and focusing to the market but new family, job and life got in the way of keeping it up to date:-( lots of players now doing it better and smarter than I did.

[PRejto]

Fantastic Chris!

[niko]

Chris,

I didn't realise it was you that brought it to light.

Given that, I just want to thank you. I found it seamless and easy to use and it never missed a trick.

I find the other products okay but I liked yours as it was what I cut my teeth on.

So, a big thanks

There ya go! gotta be happy with that Chris!...rather familiar colour scheme there too :whistle: ;) and you know...probably didn't even need that much exposure either, you're just used to those puny little APO's ;) :lol: 10" at F3.8 is a far cry from 4" at F5 even, speed and aperture rule ;)

Stunning image Chris, thanks for sharing.

[RobF]

Very promising start with the AG10. Top stuff.

[Meru]

*Drools*

And people ask why do we bother with Mono. Enough said! Great work!

[cventer]

Thanks. Very true. Never got same quality of images out of my dslr's



Thanks. It's certainly a very capable instrument that I am very happy with.



Thanks for looking



That Mike. You are right on exposure but I wanted as much oil and sii as I could get. Once I did the stretching though I realized I was not getting more email than I had out of half the number of exposures.




Thanks Niko.

Top shot thanks for sharing

[White Rabbit]

Beautiful shots I love the colour.

How do you find the 8300? I'm thinking of getting one.

[astronobob]

:eyepop: Outstanding stuff ! ! !

[cventer]

Thanks Trevor

Appreciate the comments. The 8300 is a great chip for wider field shorter focal length imaging. My only complaint about my setup is the cooling in our hot summer only does about delta -35. These chips really need -20 or more to combat noise and its not too often I get below -20 this time of year.



Thanks. Glad you liked.
