Last night I achieved first light of sorts.
After fine tuning the polar alignment, using a broomstick as a crowbar for nudging the pier supports, I went on to tweak the collimation and finally I even did a bit of lunar imaging.
It wasn't smooth sailing though. The mount in this configuration is much more prone to vibrations and resonances. I was driving the RA axis with an Arduino Uno/DRV8825 and getting vibrations that were interfering with the imaging.
Once I changed from 1/16 micro stepping to 1/32 and adjusted the current draw, things were ok, but I will need to do some vibration dampening work.
