M42 - The Orion Nebula

21:01 9/1/2009 UTC

Very cold night. I haven't been out imaging in such a cold weather yet. Usually I don't take my gear out if it is below -10°C, but this time I just couldn't stay home. Sky was very transparent and we could easily see stars just few degrees above horizon. Too bad I forgot my SQM home. I was planning to take some 1 minute exposures, but cold had done its magic on my eee battery and I did not have opportunity to fix overexposed core.
