M42 - The Great Orion Nebula
False Colour Narrowband

The Great Orion Nebula (M42) is a true showpiece in the night sky. It is
easily visible to the naked eye as a fuzzy patch in the sword of Orion, and
is a beautiful sight in telescopes of all sizes. It lies fairly close to our
part of the galaxy, lying some 1500 light years distant. The center portion
contains a tight grouping of stars called the Trapezium. M43 lies just above
the Trapezium region, and another bright reflection nebula called The
Running Man Nebula is near the top of this frame.
This image is a false colour was taken through the narrowband
filters Sulfur II, Hydrogen-alpha, and Oxygen III, mapped
respectively to red, green, and blue.

H-alpha Enhanced RGB

This image is a blend of RGB data with Hydrogen-Alpha data. The RGB was
blended with the H-alpha to form an artificial luminance layer, and the
H-alpha was blended into the red channel of the colour layer.
The blue channel is very weak in this image due to a thin layer of clouds
that rolled in. Only 10 minutes was usable.
