The difference a day makes

[John]

Last evening I had some lovely views of Jupiter at around 200x with my ED120 refractor. Really steady and at times I even found that 250x was delivering great details.

Fast forward 24 hours, same target, same scope, same eyepiece, same clapped out observer and it's like observing the planet through a shallow stream of moving water. Constant shimmering and shaking even at 150x. I can see the main features but with nowhere near the clarity that this time last night was delivering

I guess the Jetstream must have moved over my area in the past 24 hours.

Wouldn't it be boring if we knew what to expect every time.?
