Finally! This is a composition I tried to capture on a few occasions with my Sac10 CCD imager. Never had much luck because the SAC was not very sensitive at all.
Now here's a shocker. I upgraded my 7D to a stock Canon 30D (unmodded) and it will pick up NGC 1977 in 30 seconds, whereas the Sac could not do so in 2 minutes! The one main difference in the two systems is that I used an IDAS LPS-P1 filter with the sac10 and now have a CLS filter for the EOS 30D
Anyway, here's the shot of M42, M43 and NGC1977 (Running Man).
M42 is the brightest star forming region in the sky, situated a mere 1400 light years from Earth, so what you are seeing is what the nebula looked like 1400 years ago. NGC 1977 is a much dimmer reflection nebula.
