ngc281-The Pacman Nebula

This is my first attempt at a narrow band colour image. Three separate exposures are taken through the filters Ha, OIII and SII with an Atik 314L+ CCD camera and combined in MaximDL and processed in Photoshop.

The first image is in what is known as the Hubble Palette, where the SII -> red, Ha -> green and OIII -> blue

These images images consist each of 3 hours in 10 minute exposures for each of the three filters taken over three consecutive nights 23 - 25 July 2012.

The version below, which gives a more conventional appearance only uses exposures from two of the three filters.

Ha -> red, OIII -> green and blue.
