That's a lovely flat field Marcus - love those L lenses (poor man's Taks!!
)
You've captured a nice amount of detail but I'm sure you could push it some more.
If your situation allows, try increasing sub times to 5mins and up the iso to 800 (1600 if you're brave), also take some Flats.
You'll also need some shorter subs to act as Masks for the blow out of the central region of the nebula which will occur with increased exposure time.

Great work mate - you'll soon be trying to push this lens to the limits.
Go for M42 - it'll be great.
Cheers
