A clear night comes to an end.
A pretty typical view of the sky here in Seattle. I was imaging M81/82 galaxies when this was taken. I was just about to give up for the night as seen by the sky. The night was clear, but hazy, then high clouds came in. Not a super good night, but we take what we get here.
The weather instrument is wireless to the house, and usually isn't a problem since it's on the bright side of the observatory and I don't view much toward the west over the bright city.
