Hi Bill,
Great to meet up at Stirling!
As discussed offline, I’m really pleased that you’ve got Steve Evans’ rotating shutter system up and running for long-duration operation. All members who knew Steve will be delighted to see any results you obtain with this kit.
Perhaps we can locate a paper or report by him documenting its chop rate etc., although I fully agree with the need to check and confirm its current performance.
Have fun!
Alex.
