Description

Another M42, this time in LRGB. I was wanting to go a little deeper to get the faint dust and gas that lurks in the background. Very short exposures were captured to preserve the trapezium area. Only the best were selected to maintain resolution, in a sort of lucky imaging type technique, despite the use of a CCD not being ideal with higher read noise and longer download times than a CMOS. For a more in depth description about the physics please see the emission line version.
