Condition wasn't great. But improve as Saturn went higher. But clouds came in after an hour of imaging. It had been cloudy for the past weeks. I was fortunate to get a clearing this evening!
Saturn is getting bigger and higher. The dark spot in Saturn is Titan NOT it's shadow. Titan transits are very rare! And I'm fortunate to be able to view this. There are 3 more transits for the year. The one on February 24 will be a rare quadruple transit!!
The images on the right are LRGB images. Note the white spot below Titan. Is this a white spot or an artifact? Note the bands in Jupiter.

Here's my image + report of the titan transit. Unfortunately clouds came in
from the South West and my night was cut short. But I was able to capture 3
frames, and below is an animation showing Titan just on the edge of the
disc, and then crossing the face.
