Lunar dome spotting from the window-sill. 26/05/2018

The moon phase, nearly full, wiped out any prospect of DSO observing tonight, but it seemed ideal to do a bit of dome spotting.

Domes tend to be small, and that stretches the poor little window-sill ST80 to the limit.

Anyway, for what its worth here is an image of 3 of the Gruithuisen domes. Mons Gruithuisen, Gruithuisen  gamma and Gruithuisen delta. You can tell that they are raised domes as their shadows are reversed to those of craters.
