10 september 2023

Good night with the 6-inch, average seeing but good enough for this scope.  Took far too long to do star alignment but once dialed in had easy finding.  Wasps were congregating in the pier support, so I sprayed them.  At the end of the night I noticed a very large wolf spider had somehow created a web from the telescope to a nearby bush -- I sprayed that too.  'Tis the season and I'll need to take a careful look for them as I handle the scope.

STF2851 AB: 152; 125x: Faint, 1 Dm pair, wide.  65% PRO, 1,031 AU WS, 1.0+0.9 Msol, and the RVD 0.2 < EV 1.8.  It is likely binary and needs an orbit.
22h 01m 41.08s -11° 59' 30.2" P.A. 121.00 sep 19.1 mag 8.74,9.07 Sp G7V+G9III
