Whilst imaging last night; during my frame and focus routine, I noticed a strange anomaly below Betelgeuse that I can't explain.
I thougt it was a dust mote or water/frost spot on the CCD; though when I slewed an took a 10min image of the running man; the spot wasnt there.
From memory I slewed back to Betelgeuse, the spot reappeared.
This was at 11.51PM WST Dec 22nd 2009.
I looked for a reference on the web but didn't find anything that matched what I was seeing.
Here is 1 x 30sec capture.
