Dear Tom,
Was anyone talking about photographic techniques? We were considering
the precautions / choices necessary to get optical detection methods to work
OK for very small movements. How would your method cope with movements from 1
sec of arc down to maybe 1/100 sec of arc? I would be very interested to read
your calculations.
