Cost neutral upgrade/exchange

[saysme]

I have 12" skywatcher on my eq6. Not my originally intended scope but what a bargain at the time. While I absolutely love the viewing and my images are progressing. Lack of transportability is really limiting my access to club events and dark sky's. My best viewing is literately 10m from a street lamp, and limited due to same to the ESE - NNW sky's. Darker sky's out the back but reduced sky and complete setup required each time. I'm looking for a cost neutral imaging scope that will be optimum for my eq6. I would like to do more deep sky photography so an OTA suitable for this would be ideal. What's it worth? What's a fair exchange - I guess whatever I can get.

Penny for your thoughts.
