Omega in Hubble palette

Took advantage of a beautiful clear night in Sydney last night and got a few hours of M17. The seeing was great too, especially early in the night.

Ha – 11x5min + 3x10min
OIII – 9x10min + 2x15min
SII – 1x5min + 8x10min

SW 120 f5 / EQ6 / Atik 314L+ / DSS, Startools, PS

Bigger and less compressed version here: http://hughsblog.wordpress.com/2013/...-omega-nebula/

Thanks for looking

Hey, like the colour palette and although many like to process it out I am partial to the presence of some magenta stars too, has some impact and kinda makes it look more like an early HST image, which usually showed magenta stars too because it is an expected side effect of the SIIHaOIII blending

Cheers Mike, I totally agree, I'm a fan of colourful stars as long as the image stays balanced. I made sure with this one that the SII data was captured when m17 was near overhead and I was lucky the seeing was good, sometimes the stars in the SII/red channel can be hard to wrangle.

Hugh, it’s nice image, but it looks like there is somewhere a small issue with the chromatic aberration.
Otherwise, beautiful.
Thanks for sharing.

Thanks Ian, I think the colour fringing on the stars is mainly because my OIII (blue) channel had slightly flared stars and while attempting to fix them in Startools it's shifted their position slightly, the OIII stars are still quite fat and soft. Also I think I didn't do a great job of aligning the channels, might have another go.
Thanks for the comment

Love your image Hugh, great detail. How you have managed to remove core brightness, yet natural hue remained. Regards

Thanks Steve, it's certainly ended up looking different to most other images I've seen of it

Thanks David, careful developing in Startools and lots of adjustment layers with masks in PS, and it doesn't hurt starting with 16bit images!

Thanks Rod


Also I re aligned/registered the channels and updated the version on my blog, it fixes a lot of the fringing but my OIII(blue) channel is still a bit soft.
