Well done!
Thanks Mike, the difference between the two data sets is an excellent example of what active cooling can deliver.

Thanks Chris, glad you liked them. There are still some more opportunities this apparition to image shadow transits.

Is it just me, or is the shadow on Saturn quite a bit oblong, even allowing for seeing etc?
Thanks Rob, the oblong shadow in the first animation is due to instability in the boundary layer of air at the surface of my primary mirror, due to the temp of the mirror being more than .5 C above ambient and also from the air flow caused by the cooling fans of my active cooling system.

In the second animation the mirror temp has stabilized at .5 C below ambient and the cooling fans have been turned off long enough for the air currents around the mirror to settle.
