What a great effort and result Steven
I particularly noticed the complete absence of the multitude of young stars that appear in IR images of this region. That's to be expected of course, but it's still a fascinating contrast if you compare for example with my recent NIR image of M42 here:

Your UV version almost looks like a 'starless' rendition in comparison. It really highlights the difference in wavelength that these features are emitting.
I'm thinking it would be pretty cool to create an animation of M42 images, showing the transition through the spectrum from UV to IR.
