Last night I mounted my K5ii with Sigma 50mm 2.8 Macro,on my EQ5. This was not counter balanced. It was also tracked but not guided.

I set the camera to shoot 60 second subs at 1600iso and f2.8. This is 30 light subs, 10 darks and 15 bias calibration images. The lens had a 48mm SV Bony UHC light pollution filter on.

I the pointed it at the cosmos, in the region if the Pollux Constellation...

See how many Nebulae you can spot!

These next two are to demonstrate the power of a Light Pollution Filter, in this case a UHC (Ultra High Contrast) Filter.

A 'value invert' is very revealing!
