Thanks folks - I was pretty happy with it.

The idea of the two durations was to emphasize the nebulosity of M8 & M20, and the deep yellow colour of the background starfields using the long (5 min) subs, and then use the short (30 sec) subs to cut back the glare of the bright stars and keeping a nice round shape to them.

But in post-processing, I found that I could probably have done just as well with more data from just the longs, and the rest of the work via masking. It seems a rare time that more than 1 exposure length is actually really needed (M42 core and...?)
