I sign that it has been done so well! 
I have always wanted to try a remote imaging session!

Thanks for the comments Gary.
The trick to colour management is to closely monitor colour saturation as you alter image brightness through curves/levels/etc. Any changes made to image brightness should be followed up with colour saturation tweaks. If you haven’t calibrated your monitored, I would highly recommend doing so – especially for gama. Also, don’t set the final black point too high, leaving some unused space. Raising the black point to create a very dark sky background sounds attractive to bring out contrasting nebulosity, but the sky is never inky black so it’s important to portray this. A better way of handling this is simply to increase the mid tones.
I highly recommend giving remote imaging a go. You “own” that data you collect - there are no royalties. The global rent a scope folks are pretty good value. You get access to instruments in both the northern and southern hemispheres so you can image what, when and how you want. So if its cloudy where you are, get online an image anyway. Thanks again.

Cheers Phil.
Other than deconvolution on the luminance channel, no other sharpening was performed (I turn off sharpening in DDP also). I’ve found that if you use high-pass overlay selective mask of around 5 pixels and highlight the features you want to emphasise, it looks like the image has been sharpened but in reality its simply contrast adjustments. This avoids the nasty looking crunchy stars. Some pretty cool stuff can be done in PS.

Well done.
BTW you can never be too sure with these Ultra Sounds, there could be twins in there hiding behind one another !
Excellent work mate !! |
Thanks Andrew. Hope its not twins…it may end up doubling the processing workflow.

As I mentioned in the original post, I had trouble with the red channel gradients (even after flats had been divided). These were a headache to deal with as the RGB combine resulted in a red cast dominating the background – very ugly. Attach are to before (left) and after/corrected (right) red channel images. To correct this I created a subtraction image in PS then subtracted it from the original using pixel math. This was rather “clunky” and time consuming, but delivered the desired result. I don’t know how others do it – if you think you’ve got a better way, then I’m all ears.
