M42 - low level
M42 Orion Nebula (NGC 1976)
A rare "southern sky" shot (amidst the street lights - arrrgh!)

Magnitude: 5.0
Location: Orion
Date: Oct 1/04
Exposures: 230
Exposure length: 1 second
Amp on setting: OFF
Brightness: 80
Gain: 50

Notes: I set up in front of the house for this one and was flying blind amidst the streetlights. Dark adaptation is a wonderful thing. Without it I had a VERY hard time finding my way around the sky. This first image is with a low amount of histogram stretching.

M42 - med level
M42 medium adjustment level
The same AVI data, but with the histogram adjusted differently to bring out the nebula detail.

Details: as above

Notes: Significantly more detail of the nebula! Let's try one more...

M42 - low level
M42 maximum adjustments
Same AVI again, processed to bring out maximum detail.

Details: as above

Notes: Wow! I think I need a focal reducer! It's now obvious that this nebula is larger than the field of view.
