Nice! Without tracking does one need to follow the 500 rule? I love getting stars into the same FOV-- what's the ideal shutter speed and focal length to use for that (and non streaky stars and non blurry moon)?

For a 24 Mp camera the rule of 500 is way to slow. The first picture, which shows the moon emerging from the hillside at about 12 degree elevation, was taken from a fixed tripod with the 200mm lens using 0.2 sec. If you expect pinpoint stars, 0.2sec already corresponds to a one pixel sky trail, i.e. the rule should be  shorter than 50/f[mm]=0.2 seconds. The second shot (10sec, 200mm at f/5.6 iso200) was on a star tracking tripod, This was part of a  sequence of one 10 second shot every 60 seconds with an intervalometer.

There is enough time to get ready for the next eclipse.
