Description

Starting my M42 for 2013 and going for an HA RGB image this time. My last effort was all NB and really not happy with the colors in that one so wanted to try a more natural approach this time. This is the HA done with subs of 10 sec, 120 sec and 300 sec to capture as much detail as possible. Now all I need are a bunch of clear nights to capture the RGB!!
