M38 and the Flaming Star Nebula

It was a very cold night, -8 degress Celsius at the observation site near Dângău Mare, although the car’s thermometer indicated -14 at some places on the road back. While contemplating the beauties of the southern vs the northern sky, I imaged this vista in Auriga, which to my surprise turned out to look very nice with my setup. The frame contains, among others:

  • M 38 or NGC 1912 [open cluster] 6.4m
  • NGC 1893 [open cluster+nebula] 7.5m
  • IC 405 or C 31  Flaming Star nebula 10m
  • IC 417 and NGC 1931 (the Spider and the Fly)

Technical data: 26×2 min, ISO 1600, Canon 1100D mod, Canon 200mm f/2.8 @ f/4, HEQ5, Dângău, Cluj. One step of the processing was my star reducer.
