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: 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
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?

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

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.
Excellent Chris! I like it a lot 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.
Some additional graininess visible in the full res in patches - sharpening artefacts?
Cheers, Marcus
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
your site reminded me what a shame it is that DSLR Focus was never updated
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.
There ya go! gotta be happy with that Chris!...rather familiar colour scheme there too and you know...probably didn't even need that much exposure either, you're just used to those puny little APO's 10" at F3.8 is a far cry from 4" at F5 even, speed and aperture rule
