I din't know anything about astro photography, but this one looks very good, indeed!

David,
did you do a dark frame subtraction ?

Your camera needs repair, too many dead pixels (white spots) 😉
On a serious note, tech details? On an artistic note, too saturated (or was it indeed a volcano eruption?😉 )

I am not sure what that is. If you mean long exp NR, then no
tech details?
This was a number of frames, 8 I think, ranging in ISO from 800 to 12500 in half stops and then an HDR merge in LR. D7100 with 10-24 @ 10 mm, f/3.5, 30 sec exp. I was thinking that the merge might mitigate some of the noise and I was curious whether the frames would end up being aligned properly.

Your point is well taken and I am guilty of slidercide! I don't like that orangish blob lower left in Milky Way or the bluish tones towards the top. Seems that the image can be pushed just about anywhere with WB, tint, etc. When I realized this, I wasn't going for accuracy and I was so excited just to see a result, plus a glass of Jack Daniels, well it got pretty wild. At one point, I thought the North Koreans had taken out Phoenix ;) Most of the time when we look at the stars, we are seeing in B/W (rods in the retina) so we don't really know what the color should look like although I realize that it can be scientifically measured, of course.
Below, is a single frame image, same setup, 30 sec @ ISO 1600. My subjective impression is that there may be somewhat less noise, but I did apply a Topaz filter. Maybe a little less saturated for Slobodan's taste as well. I think I am still trying to figure out technical stuff and will worry about aesthetics later; gotta walk before you can run. Thanks for the comments

Posting "final" version. Manually aligned and merged four frames (ISO 800, 1100, 1600, 2200) because that's what I had and wanted to practice what I had learned at lonelyspeck.com. Learned a lot and had a bunch of fun! Thanks for the comments.
