Saturn 6 Sep 2023

Apparently a good night, maybe with too much wind from south.

The session started with some tests on the airy disk. The purpose of this first set of videos was to identify possible problems with the optical set, I’ve always noticed that the B channel is much worse than the R or IR one.

Yeah, it seems the scope was a little bit misalligned…

And finally the wide-field version, double exposure, June for the planets and one for the moons.
