From northern mid-latitudes, Cassiopea is a very nice constellation to view in the autumn.
Look in the NE skies for the sideways "W." This photo covers the area just south of the middle of the "W", Gamma Cas, also known as Navi.
The photo has north to the left, and just to the right and below HR 266 are a pair of stars that, to me, look like Cat's eyes.
This is ARG 3 consisting of two stars, SAO 11489 (magnitude 9.41, unknown distance) and HD 236582 (aka SAO 11490, mag 8.51, 236 ly away).
Not sure if this is a physical pair since distance to SAO 11489 is unpublished. They are 20.6 arcsecs apart.
