Saturn + moon May30UT fairly good seeing

There was some onshore wind to blow away the unstable air over the town and I got some interesting, but variable quality, lunar shots (deep red filter) while waiting for the scope to stabilise and for Saturn to get some altitude.

The wind eventually blew up a bit much though and the scope was bouncing around a lot. I took the attached Saturn sequence anyway, since the underlying seeing was not too bad, with some fine detail when stable. Stacked about 25% of images since many were damaged by scope motion. Pushed the processing a little to bring out what looks like a white "barge" on the edge of the light coloured band.

I then pulled down the system and moved it into the wind shadow of the garage. The wind changed as I was moving the scope and the new position ended up being no better than the original, except for significantly degraded seeing courtesy of the new wind direction.

thanks for looking. Regards Ray
