M20 taken at SPSP14

Hi All - it has taken me a while to finish processing this as I've been busy with other things. I struggled badly with the colour-balance in this image so I tried stacking raw subs (rather than converting them to tifs first) & it seems to be a big improvement.
This is my first attempt at this object (since a failed effort back in the film days) & probably my best deep-sky image so far.

14 x 1 min unguided subs at ISO 1600 through a Pentax K-5 attached to an ED102 on a Vixen SP mount.
