The transparency and the stability were good.

Good conditions on this morning (in strong twilight) showed the action in the
NTrZ well. The dark spot and the projection were obvious visually.
The imaging adopts a technique I used successfully last year when the planet was
very low, of a relatively short focal length on the C-14 (1.6x Barlow only),
17fps rate, and IR 742nm and blue filters used only to construct a
similar-to-true colour image.
