Description: "Print" version. Since prints always come out darker than how I see them on the screen due to the inherent differences between subtractive vs additive color, I always bring up the exposure a bit in Photoshop before printing. When I did that with this photo, it revealed some interesting structures (at least on screen, they were mostly lost in the print). The trade-off to raising the levels is that it made some of the color transitions more blocky (less smooth). It is probably revealing the limitation of only 3 hours of integration on this so far. Anyways, if you are reading this I would love to hear your thoughts on this photo and/or calibrating astrophotos for printing.

Description: Using the Selective Color tool in Photoshop. A more traditional Gold and Blue look.

Description: A more "natural" look I think by shifting towards red / magenta. Might be my favorite so far. What do you think?
