After an evening of playing with our associations new DMK21AU04.AS camera in Manfred Böhler's observaory, I set up my equipment at home to use the clear sky to do another picture of comet Lulin before the clouds and the moon spoil the show:

After waiting in vain the whole evening for the sky to clear, I went to bed. But I was not sleeping too well, and when I awoke at 03:00 am, I saw some starst through our bedroom window. I grabbed my 15x50 binoculars and easily found Comet Lulin below the constellation of Leo, with the 15x50 the tail was easily visible, even through the suburban sky that I have at home.

I managed to get myself dressed and set up the Super Polaris mount on our roof, and managed to get the following images. I stopped imaging when clouds rolled in. At 4:30 I was back in bed, only to get up for real at 06:00 - yawn!
