Tarantula with a DSLR

Hi all!
This is my latest (and personally, my greatest) astrophoto!
Boy, was this an absolute nightmare to colour balance! the DSLR's low sensitivity to Ha gave me a hard time trying to pull out red to get a more natural colour balance. Taken from my bortle 6 backyard, with 4 hours total integration time. The 200kb limit makes this pic look kinda crap. (links to full res below)
I have included a green version (without pushing the red), and a red version that more accurately represents the colour. which one is better to my eye? not sure!

Gear used/image data:
CGEM mount, autoguided
Takahashi MT-160 at f/4.9 (lovely sharp stars with this scope! spacing is a tad off though, not sure how to fine tune it though. )
Canon EOS 700D
40 X 5 minute exposures
ISO 800

Anyone know how i can fine tune spacing? could i (for now) try unscrewing the t-adaptor a tad and see how that affects it?

Sorry but no idea about your spacing problem.
