The following is a quote from IOTA I would much prefer the largest number of observers using video to time occultations to an accuracy of 0.1 second guaranteed, and often to 0.05 second, than to have only a few who have the electronic background to achieve absolute timing accuracies of +/-half a video frame. In other words, don't struggle to get 1/60 sec when 1/10 sec is good. The gain is not that great.The important thing is to get a record submittedRon
