It's also a popular target for astrophotographers as it is very easy to locate, and because of the aforementioned inherent brightnes, which means that even short exposures will reveal colourful nebulosity. Thus it was one of the first things I took an image of after equipping for astrophotography, and after some experimentation out in the cold under dark skies the end result was the following:

The frames were captured under a moonlit sky, so not ideal conditions admittedly, but it's always worth a try!
Unseen here in the overexposed core of the nebula is a very young open cluster known as the Trapezium because of the configuration of its four brightest stars. Above the main nebula can also be faintly seen NGC1973/5/7, The Running Man, which is a blue reflection nebula that is part of the same massive molecular cloud complex as M42.
