| Quote SolarLiner (  ) and it doesn't reproduce any Einsteinian Rings as well
Isn't that an Einstein ring around the black hole?

| Hmmm, yeah you're right! But only the first is shown, on the original render (8k, I downsized for web ^^) I don't see the other ones.
My plan is to try and render an accretion disk a la Interstellar, and see how well I can do it. Smokes simulations are not my favorite thing to do though ...

| I've finally got three cameras in service, which are now properly aligned and calibrated. Which means that I can reproject and stitch the images as I like, and I have almost full coverage of the sky. The three cameras are run by an Odroid U3 credit card size Linux computer (same chipset as the Samsung S3 smartphone) with 3x3 TB disks attached which can hold approximately four months of continuous video.
I'm not going to embed what the combined video looks like, not even with spoilers, because the images are huge. Here are two projections: equirectangular and fisheye.
If anything happens in the sky, I should get pretty good pictures of it now and can pinpoint it within a few arc minutes. I hope to get more systems like this in operation by the next dark season.

| Quote Billy_Mayes ( ) I made this in Blender:
That deserves more praise!
Are the red fragments artificially constrained to stay on the platform, or did you run the simulation, lock in the fragment paths, then rewind and colour the platform-stayers red?

Thank you! 
I ran the simulation, them looked at the ending of it and colored the blocks that stay on the platform red. It's really easy but looks cool.

| WTH!!!!!! is wrong with norwegian skies!!
That's trully amazing, what's going on exactly? I would love to use my polarizing filter to see if those colours are also associated with different polarizations.
Just wow

The clouds were visible all day. That shot was taken about one hour before sunset.

| I've seen iridescent clouds, but never nacreous/pearl clouds, nor such a fine image of them as yours. Truly marvelous, and I bet it was an amazing experience in person.

| Iridescent clouds literally fades in comparison with nacreous clouds which are blindingly bright. That makes them a bit difficult to photograph and get something resembling what's actually seen. The human eye has a large dynamic range, but cameras don't. Here's another picture of the clouds with no post adjustments. The clouds are greatly overexposed, yet the foreground is very dark.
My image also made it to the Optics Picture of the Day.
Nacreous clouds are not very rare here because we are often downwind of the mountains, we see them a few times every winter, but it takes a number of conditions to be right for them to form. This display, however, was one of the better I've ever seen.
The clouds were still there this morning, but disappeared later.

| Nowhere near as beautiful or rare, but kind of interesting atmospheric dynamics wise: an orographic cloud (produced by low pressure on the lee of a steep slope during a windstorm), with vortex shedding.
Edit: Whoops, should not have embedded that in the forum.
