Yes. They are a little bit orange. I did no want the California to be very saturated, so I just keeped them in that tone. Anyway, I found that the Provia film has a good response to H-beta and OIII, and that color could be due some emission in that wavelenghts. BTW, see in my "old" wide field images the one taked with the 135mm in the southern Orion field. You can easily see a big difference between the reds of the Flame, the Horsehead and M42.

That is an advantaje of PixInsight. When you are working with 32bits per channel, even when the original has only 8bits, the final histograms are very beatiful at only 8bits. If you look them at 16bits resolution you'll see the gasps and spikes.

About the stars, I was able to bring a lot of faint ones with deconvolution. I'll upload in a few hours the digital processing page, and you'll see that in a comparison.

Funny, isnt? :-)
