A clear night but with average seeing and a steady marine haze, so I used the 6-inch. It took a while to star align, which was frustrating, but eventually settled in for a decent night. Ended with views of the just-past full moon, with plenty of interesting crates and mountains on the moon.
STF 834 AB: 152; 125x: Very wide near equal. -23% PRO, it is not binary.
06h 04m 34.24s +30° 14' 04.0" P.A. 310.00 sep 22.8 mag 8.61,9.38 Sp A dist. 25.52 pc (83.25 l.y.)
