Fooling myself trying to split this one.  Proof that sky is still not stable enough.  Will save this one for another evening on the big refractor.

Seeing: 8-9 <1-10 Seeing Scale (10 best)>
Transparency<1-10 Scale (10 best)>
Location of site:
Site classification: Village-backyard
Sky darkness
: 4 <Limiting magnitude>

Conditions: bright moon low in the
southeast
Telescope: Celestron C11
Eyepieces: Pentax SMC XL 40mm, TV plossl 20mm, China plossl 10mm
Magnification: 70x, 140x, 280x
  
With a separation of 0.8" and almost equal brightness of the components
this is not a real nutcracker, but these two bright stars will easily
merge together with lesser seeing of bad optics/collimation. This
evening the split was easy for the C11 at 280x. Almost continues a clean split,
only now and then the seeing degraded and resulted in an elongated image of the
pair.
