The first night of the winter where we had frost (25°F) at the Dutch Observatory. The humidity was high, 85%, and I had to interrupt twice to keep the frost off the corrector plate.  I am pretty happy with the image at average seeing and transparency.  Clouds can be seen over Cydonia extending to Niliacus Lacus and Mare Acidalium.
