Knowing how software development works I try not to ask "are we there yet?" too often Probably some time in the next couple of months.

Thanks, Colin. Yes, that's a nice colour balance if you prefer the redder end. I think the very blue images of globs that we see aren't very realistic.

Last night, encouraged by Marc Aragnou's slightly wider field image of omega, and dismayed by our omega overflowing the field, we did a tight 5 panel mosaic to get just that little bit of background. There are some bright G0 and G5 stars in the field. That might help a bit.

NASA has an ageing Hubble shot of the core of Omega. They say that most of the stars in the image are sun-like stars. They've chosen to make them yellow-white, rather than white. Subjectively, we like that, but dislike their intentional over-saturation to bring out the smattering of blue stragglers and red giants.

We reckon at making Omega (or giant ellipticals, for that matter) look positively blue is a common mistake which goes against the seniors-card carrying astrophysics of these venerable old objects. We agree with Colin that D looks very pleasing.

Thanks for your timely discussion and examples. It will help us with our processing.

Thanks for the well thought out comments, as always M&T! It will be nice to have a scientific, yet flexible, basis for colouring images
