It's 5 nm. The 10 sec exposures are for the Trapezium stars and the surrounding area. More than 10 seconds and the Trapezium stars would begin to saturate and bloat out.

Roland,
At the risk of opening up a can of worms (sooo many opinions on this matter), do you mind if ask what the passband width of H-alpha filter you used for this image is?  It seems like it would necessarily need to be fairly wide with 10s subs.  But then again, M42 is pretty bright.
