     Not so! Look for a $10 Casio stopwatch or wristwatch with "lap" times on the stopwatch functions, most of them have this and will say something like "lap/stop" next to the same button if they do. Then just can start the stopwatch running exactly on the hour, so the stopwatch 00:00:00 matches the exact hour. (If you are off, no problem, just note the difference and carry that as a constant.)
     
    Then using the LAP button at the moment of observation, you will freeze the "correct time" except of course you'll need to add in the real hour, to the minutes/sec/decimal showing on the stopwatch. When you hit LAP a second time, the watch snaps forward to the running time from when the stopwatch was started. Next time you hit LAP, it again freezes the display. Again, without changing the setting of the stopwatch.
     
    As you alternate, you can freeze the display, note the time, snap back to real time, freeze again, etc. to make note of as many frozen times as you want.
     
    The trick is to memorize exactly which button to press, or buttons to press. Once you get that down, it becomes quite simple and reliable. I've used a bit of velcro to attach a stopwatch with the correct button directly under my thumb (on the arm) and it works very nicely, no need to take your eye away from the scope at all, just squeeze, and then move to read it.
