Ok guys I've taken you suggestions and applied the following.

1. Piggy back on LX200 Alt/Az config. ie more stable tripod and tracking.

2. Changed lenses from EF 80-200 mm to 28-90 mm w&wo 2X teleconverter set to approx 68 & 135 mm, ISO 1600 & 800, f/5.6 & 11.2, Tv 60 - 180 sec, . This is the worst image but they all show some sort of rotation over the same field area down to Tv 60 sec, 68 mm in both ISO speeds

The change of lense seemed to take care of most of the flare (I think I need to be more careful when I let the cable release go after activating the shutter), but I'm still getting rotation at the outer 1/3 of the sides and bottom edge.

Any suggestion? Pec/Training Dec axis maybe. I guided using an image from ToUcam mounted into a 2X barlow centered on my video review prog, though all captures. I didn't have to do much in the way of guiding changes.
