Date & Time: 2135 UTC, 23.Feb.2001 Seeing: 4-5 <1-10 Seeing Scale (10 best)>. 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 FOV: 5d |
Very easy to locate, although
it is currently rather low in the sky. Star hopped from alpha Boo -> Eta
Boo -> target. Verified target with help of SMP charts: Delta forms an
almost parallelogram shape with 50 Boo, TYC 2566-1637-1 and TYC 2566-1638-1.
The main component (mag 3.5) dominates the pair, but the dimmer component (SMP: TYC 2566-246-1, mag 7.8) is visible (averted vision helps) and thus the pair splittable. Rather wide separation. Delta has a distinct red colour. This pair probably looks much more impressive in a telescope and higher mag than in my Vixen binos. Limiting magnitude at this
time: I can *just* about make out the 8.20 mag star TYC 2566-445-1 closeby.

Quite easily located at
the upper right corner of a stretched out
square. Both appeared white, as most did behind the night's moonwash.
