Description

The witch seems to be gazing into her crystal ball in this one.

Orion is positioned really nicely in the early evening for me, but falls behind the trees within a few hours and I've been trying to take advantage of its position. This panel was just over two hours, but I found the variation in colors to be really interesting, so decided to post it.

Just over 2 hours of 120-second subs with modded Canon 600D, Rokinon 135mm f/2 at f/2.4, and iExos-100 mount. Guided via PHD2 and dithered every three subs, but the -25C ambient temperatures really kept the sensor noise under control. The blotchiness was from my mediocre skills in removing stars and re-introducing them.
