I’ve noticed 3 types of seeing when attempting to take hi-res images of the Moon and Jupiter:
  • Slow, long wave length undulations with a small amplitude which give me the best seeing. Typically I can see the 4 craterlets on Plato’s floor.
  • High frequency, short wavelength fuzziness which destroys all details.
  • Fast, long wavelength undulations with a large amplitude akin to looking through shallow water. The lava lamp effect. Images look soft and smeared with no detail.
Cheers

Dennis
