M42, the Orion nebula.

Right Ascension = 5 : 35 : 4 (h:m:s), Declination = -05 :27 (deg:m)
Magnitude =4, Size = 85.0x60 arc minutes

M42 full field view.

The above image is the full field F1.95 image. It consists of 4x5seconds red + green + blue scaled, DDP'd and median filtered in CCDops v5.21. I need to get longer exposures to reduce the noise. This was a late test image that i am posting until I get it better. March 13, 2002.

M42 triad closeup view.

This image is taken at 1270mm f6.3 making it a 12.7 x 9.5 arc minute image. Red = 20sec + green = 30sec + blue=40sec) at -20degree C cooling. The only modification is each was auto-dark, DDP'd and medium sharp before RGB combining in CCDops v5.21. March 5, 2000.
