With some clear skies overhead this evening, I took the opportunity to do a shakedown of the new rig.
I have a Skywatcher EQ3 Pro - thanks @Jamgood
A Raspberry Pi running Astroberry
Canon DSLR with either 70-200mm f2.8 or 100-400 f4.5
RVO 32mm mini guide scope
ZWO 120mm mini CCD
12v leisure battery
Self build 12v power distro box (3x12v & 6xUSB3)
Yesterday, I got the focus pretty close on the guide scope - thanks @gilesco, @Chefgage& @m.tweedyfor advice.
Got the mount set up - tripod level, roughly polar aligned.
Haven't got the bits to mount both DSLR and guide scope yet, so just DSLR mounted.

Alignment - offline plate solving working
Polar alignment - image capture no problem, but when it came to rotating the mount, it was very very slow. Not sure what's going on there - must be a setting somewhere. Direct control was the same (software hand controller). Messing with this gave the clouds time to roll in.
Was going to fine tune focus on guide scope - but clouds
For a shakedown, pretty pleased with this. Even though I didn't get any images, good to get stuff working, having never done any of this before.
Pic is the power distro box
