Earlier this evening I found some good seeing just after sunset and grabbed some data on Saturn for half an hour until it disappeared behind our big old yellowbox tree into the west.
The seeing was surprisingly good, and despite my earlier declaration to the contrary there are some more colour images possible Titan shows up nicely in this image as well. Thanks to the heroic efforts of the peltier cooler on the scope there was only a 2C difference in temp between the mirror and ambient.
Here is the very first image of the session, more to come.
