Location of site: Hamburg, Germany 
Lat/Long: 53 34 N, 9 59 E 
Site classification: Suburban sky 
Sky darkness: -- <Limiting magnitude> 
Binoculars: Vixen Ultima 9x63 + tripod

Found this one by star hopping from Pollux -> kappa Gem -> delta Gem -> target. Zeta was confirmed by reference to a dim but visible triangular asterism above it in the binocular FOV (checked with SMP). These three stars are (SMP)  TYC 1357-847-2, TYC 1356-2542-1 and TYC 1356-518-1.
 
Zeta was not too difficult to split. The Moon had only just started to rise and did not hamper the observation. The star appeared red-orange to me, quite unmistakably, and the image was very steady. Its companion (which did not need averted vision to see) was a very faint, but distinct blur with no discernible colour. This companion seemed to be about the same magnitude as the three stars in the asterism noted above. Very nice pair.
 
Estimated PA is 330 degrees. Seems close to N-S direction.
