Great Orion Nebula

Ever since I bought my Mewlon 250 I have long wanted to photograph the Great Orion Nebula at 2500mm focal length... even if it is awfully slow at F/10. On NYE I finally got the chance and I'm pretty happy with the results.

The thumbnail image isn't the one on Astrobin but has been pushed past warp speed

This is 135x60s exposures, I wanted to sit and forget so I picked the longest exposures I could get without over saturating the core. The stars A-F in the Trap are all visible but the F (I believe) isn't a clear split. Could always try some short exposures one night to just do the Trap.
I've attached a lightly stretched an saturated crop around the trap. One of the good things about a slow F/10 is longer exposures before saturation.

EDIT:
Better colour version
