Zeta Her (Visual Binary, in Hercules)
Observer: John Callender (e-mail: jbc@west.net, web: http://www.west.net/~jbc/)
Instrument: 8-inch Dobsonian reflector Location: Carpinteria, CA, USA
Light pollution: light Transparency: good Seeing: fair
Time: Sun Jun 29 06:50:00 1997 UT Obs. no.: 161
Unable to split at 244x. According to Burnham's the separation was supposed to be 1.6" in 1990; with a 34-year orbital period I'd guess the separation would have closed about halfway towards the minimum value of .4", making the current separation about 1.0", too challenging for my 8-inch (at least in tonight's only so-so seeing, and possibly even under perfect conditions), given the big brightness difference between primary and secondary (m2.8 vs. m5.5).
