Bravo ! Gary. No need to do a plot with that shot. How did you go about timing the observation ? Did you look at your wrist watch then subtract one second or was a stop watch used ?

[NavList] Moon shot with artificial horizon

I was putting the cover on my 12 foot plastic pool tonight when I noticed that the reflection of the moon in the water was not wiggling so I went and got my Tamaya and took a shot using the still water in the pool as the artificial horizon.
