Hi Mark,
Nice image better than my attempt although I have not tried to push the limits as far as 3 minutes.
The bars possibly due to the flats, I had the same problem although different bands. The issue in my case was the power supply to operate the Electro luminance panel.
If you use an EL display for flats then try moving around the power supply away from the camera as they are extremely noisy switching power supplies.

Using HEQ5 Pro, Evostar ED80, Canon 700D, Svbony 50mm guidescope, ASI120mm mini autoguider all plugged into my aging Acer laptop that has 4 usb ports(bonus).
100 X 3 min exposures, 30 flats and 50 bias frames. No darks because 1) I'm lazy and 2) There seems to be those that say use them with a dslr and those that say don't. 
Processing with Deepsky Stacker and Startools.
I'm pretty happy with it but am I pushing the limits of my dslr? Or have I picked a hard target to practice on? Thoughts?
thanks for looking
