That middle barred galaxy looks like a real challenge, I had a look on line and apart from ones imaged at professional telescopes, I didn't see any great results. 

Presume you are planning on getting some more data.  Perhaps a faster telescope might mkae it easier.

But never the less, it is a good achievement.

Thanks Carole, it was a terrible imaging night as well, windy and intermittent high 'mist' messing with transparency. One to be revisited on a more benign occasion.
