I wondered what you were up to these past few clear nights Toby. Stunning image, all that hard work has paid off.

To raise all the dust to that level with a DSLR is imressive.

The colour is looking much better.;)

Hope you don't mind I had a look at the histogram of your last process and the data is still clipped, much less blue clipping but still clipped, as is the red and green ( more so the green)

I had a quick play with the colour using levels and curves in photoshop.

In the image below, the top half is the image and it's histogram after I had a quick play. Although the histogram no longer looks clipped the feint data has already been lost (clipped) as you can see in the histogram of the original image (bottom half of the image) the data has been cut short on the left side of the histogram which is the black end of the histogram.

if you go back to the raw data and avoid any clipping, the colour should come right and you won't have to push the red so hard to reveal the faint Red data.

Please don't take this as criticism, you have a great image as is just seems a shame to lose hard earned faint data.

Mike.

Toby, in the histogram window open the "channel:" drop down menu and select colours , you can also go to the top right corner of the histogram window and click on the three parallel lines which will open another window menu here select "all channels View" and "show channels in colour" then you will have the RGB histograms overlapped and below that each of the "RED", "GREEN" and BLUE histograms on there own.

Hope that helps.
