This is an average of two quick sequences that I grabbed of Saturn before it reached the meridian. In part, I wanted to compare using longer exposures using lower gain versus sorter exposures and higher gain. I just so happens that these two sets were very similar, so I averaged them into a single image. I am very happy with the results and I’m looking forward to trying this again using a camera with slightly smaller pixels (an ASI462MC with 2.9um pixels). If you look really closely you can glimpse Rhea to the lower left of Saturn and Tethys to the upper right.
