Object: M42 Camera: Meade DSI-Pro II
Date: 10/17/2006 Lens: Sigma 400mm lens
Total Exposures: RGB - 22':22':22: Subexposures: 8x8", 10x30", 15x1' each
Location: West Boylston, MA
Processing: I went nuts while out the other night and collected 3 sets of data for each channel. One set is 8" subs, one is 30" subs and the last is 1' subs. I made RGB versions of each. Then I made one RGB of those three RGB's.

Description:
M42
Possibly discovered 1610 by Nicholas-Claude Fabri de Peiresc.
Independently found by Johann Baptist Cysatus in 1611.
Trapezium cluster found as multiple star by Galileo Galilei in 1617.

The Orion Nebula M42 is the brightest diffuse nebula in the sky, and one of the brightest deepsky objects at all. Shining with the brightness of a star of 4th magnitude, it visible to the naked eye under moderately good conditions, and rewarding in telescopes of every size, from the smallest glasses to the greatest Earth-bound observatories as well as outer-space observatories like the Hubble Space Telescope. It is also a big object in the sky, extending to over 1 degree in diameter, thus covering more than four times the area of the Full Moon.
