M42- The Orion Nebula
The Orion Nebula (M42) in the constellation Orion is a star formation region and is the closest emission nebula. This image is a combination of LRGB exposures totaling 100 seconds each through a William Optics FLT110 4" f/7 refractor using an SXV-H9 detector. This image was obtained on 1 March 2008.
This image was taken on 5 March 2008 and is an LRGB composite of 10 minute exposures through the same 4" f/7 refractor using the SXV-H9.
The four stars at the center of the image are known as the Trapezium and are not found in most photographs of this nebula because traditional film-based images must overexpose this region in order to show detail in the fainter nebulosity. Click here to compare this image to my film image of the nebula. To find more information and images of this nebula visit the Web Nebulae - The Great Orion Nebula and the Messier Index - M42.
This image was captured on 8 October 1999 and is a composite of numerous 1/2-second exposures through filters in the following amounts: cyan (50x0.5sec), magenta (49x0.5sec), yellow (50x0.5sec) and white (IR filter only 52x0.5sec). The white component of the above image is shown below.
The image shown below is from a different section of The Great Orion Nebula and was taken shortly after entering the year 2000 Universal Time, while still in 1999 Eastern Time (0327-0406UT). It is composed from 44, 15-second subexposures.
A color version of a portion of this region was obtained while crossing into year 2000 Eastern Time. This image combines the above white (IR blocked) component with cyan (46x15-sec), magenta (28x15-sec) and yellow (30x15-sec) components obtained from 0441-0552UT (2341-0052 EST) on 1 January 2000.
