Thanks guys you're all very kind,
But I'm all too aware of the reason this image isn't all it could be.
I used 6 pics in a stack of 10 which showed a bit of star trailing. The good 4 probably wouldn't have been enough on their own for a decent S/N ratio - I've only got myself to blame!!!
I'm starting to throw away more subs than I keep I find and i think the EQ5 is to blame with dodgy PE in its tracking. I may try the AstronomyBoy strip down if I pluck up the courage, but from this recent article on CN it might be the way to go...
