Timings for lunar eclipses don't require the precision that a stellar occulation does. If you are within 5 seconds, you can produce usable data. On Fri, Apr 4, 2014 at 8:43 AM, Dale Hooper <Dale.Hooper@sdl.usu.edu> wrote:
I use the Kiwi OSD - which is no longer available for purchase. But, I think the IOTA Video Time Inserter - shown in the link below is what most people are using now.
Clear skies, Dale.

The NIST-F2 is stated to be accurate to within one second in 300 million years! Now if they'd only come out with digital watches to come close to matching that. Does this put amateur crater immersion and emersion timings for the next series of lunar eclipses a thing of the past? (apparently my computer's dictionary doesn't know how "emersion" is spelled). I would presume that if one is recording the eclipse on video it would be best to record the atomic clock signal from Denver via a external microphone for accuracy?
