Here is my 2010 revisit of M42, the Great Orion Nebula. This is 10x180s, 10x60s, and 10x5s subs, stacked in DeepSkyStacker and then HDR merged in Photoshop and post-processed. I was able to capture the Trapezium stars this way. Used my Celestron C8 at f6.3, PHD guiding, Canon 350D (unmodified). Captured these at my dark sky site near Woodland Altars campground 6 Mar 2010. Processed with DeepSky Stacker and Photoshop CS3. Finally, the drought is over! Back to imaging again.
