Thank you for that Julian
.
Quite an education from Doug too.
So Jetstream hey... I don't fully understand Jetstreams. This probably explains why the seeing was so terrible here in Brisbane on Saturday the 6th too then
. It was beautiful and calm that night but got incredibly windy later in the night after I'd finished observing. I was observing asteroids Ceres and Vesta and Saturn's moon Iapetus which only makes an appearance every 70 odd days. Saturn was tragic & the stars just wouldn't hold focus. But the asteroids close encounter totally rocked!
