Another clear, if hazy, night, with average to good seeing. I used the 6-inch on Cepheus Struves, and had a surprisingly good night. I didn't cover the entire constellation, but did get a good chunk of it. Viewed the moon and Saturn at the end of the night, but transparency was hurt by Oregon wildfire smoke which has blown down our way.
