Hi all, here's an animation comparing the Venus nightside image from this morning with a reference topo map. For this session we used the Uranus-M camera from Player One, it has a mono imx585 sensor. The result was pretty good considering the seeing was not very steady this morning. 
Some correlation with known surface features can be seen, particularly on the limb at right.
I've left the image uncropped at the top and sides so you can see the out-of-focus internal reflections from the imx585 sensor cover glass. At
F/4 these internal reflections are not encroaching on the image in the centre but I suspect there is some extra scatter from the sensor cover glass.
