What objects you can photograph does not only depend on how good your equipment is or how much light pollution you can filter out.  It also depends on their apparent magnitude, how bright the object as seen from Earth: Very bright stars far away can be harder to see than dimmer objects nearby.

Vsauce has a fantastic video on this topic you definitely have to see.

So what objects can you see from a light pollution zone 7? 

Skyandtelescope.com made a list of 111 objects, visible from mid-northern latitudes, that can be seen from heavily light-polluted areas.  The lower the magnitude number, the better visible the object will be.  Not a bad list to have handy when you want to start imaging one day.
