Description

Bi-color image of the Orion Nebula, using narrow-band H-alpha and O-iii filters. The data for this image is over a year old, but I have finally have the processing for this "close enough."

The image is a composite of 2 min, 20 sec., and 4 sec. exposures. I used the Pixinsight HDR Composition feature to combine the three integration times. I then used the HDR Stretch utility (6 layers) to produce the final result.

The image revision contains the H-alpha data only. It shows the outer fringes of the nebula more clearly.
