IC434 - Horsehead Nebula

One thing fun about using monochrome cameras and narrow-band filters is the near endless experimentation one can do with various combinations mapping the emissions of Hydrogen, Oxygen and Sulphur to the various RGB channels. This object has been done a lot and is very popular, but here I went for unusual color combinations to create contrasts between the different colours. Using Pixel Math in Pixinsight, I was aiming for a different "look" than the standard look. Captured with an Askar 107PHQ telescope with a 0.7x reducer. EQ6 controlled by a ZWO ASIAir Plus computer and represents around 24 hours of exposure time. Processed in Pixinsight, star reduction, and completed in Capture One.
