Most dust caps are not IR proof. So light can pass thru with phsicodelic patterns.

Tried that - or something similar. I put the camara inside a sealed dark box while the exposure was under way. So it isn't stray light. As I write this I wonder whether the rear LCD screen is illiminated during a long exposure?
The unresolved issue is the power supply. I'll have another run at it using battery only and see what occurs.
