M42 is always a great object to observe even in light polluted skies it can show some nebula. From my light polluted backyard it can be hard to pull out faint detail in nebula or galaxies, but I managed to get a small look at M43 with M42, but I wouldn't have been able to see it if it weren't for putting in the Orion Ultrablock filter. While it dimmed the stars and the background I could make out a bit more contrast in the nebula and was able to see some more detail I couldn't see without the filter. I placed all the stars, and the bright central region of M42 before adding the filter.
This was done through my Celestron Omni 150 XLT with a 32mm eyepiece for a very wide field of view. Pretty sure I had all three stars of the sword of Orion in the eyepiece.
As with all my sketches there is a video to go along with it to see the time lapse of the sketch being done at the eyepiece: https://youtu.be/bUlbsgJ4ccA
