It's disappointing when the computer modelling let's you down. You plan for a good productive night that doesn't eventuate. At least you managed to capture something. By the looks of things, you may need to shoot some flats to avoid that vignetting and hot spot in the centre. You have certainly captured plenty of galaxies in that field, so well done to you and the stars look nice and sharp.
I drove out to the outskirts of Melbourne last night for some astrophotography fun. They sky was clear but the dew was horrendous. The objects I shot were high above so the dew had uninterrupted access to my mirror and lenses!
