This isn't related to Kerbol, but I haven't seen the plain angular diameter values for the planets/moons at their semi-major axes on this thread, so here are some I've computed:
Mun: 1 degree, 54 arc-minutes, 47.56 arc-seconds
Duna: 6.3 arc-seconds
Dres: 1.4 arc-seconds
Jool: 36 arc-seconds
Eeloo: 1 arc-second
I'll post more diameters later, if I get the time to. (I should, because of Winter Break, but you never know.)
Here's a picture of what I calculated Eeloo would look like if viewed from the resolution of the Hubble Space Telescope:
