Description

Bortle 7 Urban Skies - tracking was good at 0.7as on a 2.4as/pixel scale.  M42 never rises more than 35 degrees at my latitude so it is hard to get a really crisp image but I am happy with the result anyway.

In the color image Hydrogen-Alpha is mapped to Luminance, Sulfur 2 is mapped to Green and Oxygen 3 is mapped to Blue for a unique perspective on things ...

This is part of a 4 image set that is aimed at highlighting the different features in each spectral frequency as follows:
