Thanks Hagar

your tips are welcome. I had suspected I needed to step the light down a bit more.

I'm not sure what you mean by intensity of 12 - 15. Do I measure this with the Information tool and just cruise around the flat with the cursor to check this?

I am also intrigued on how you came by the 0.2 second threshold. Is there some dark maths at work here or is it just an outcome of your experience.

To push out the exposure time I upped the target ADU to 25k. Seems to work ok.

Pete
