Seeing: 4 <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
|Got this one in the same bino field of
view as Albireo, although it actually lies just across the border in Lyra.
3 Vul is to the East. Easy to split, but both components roughly the same
brightness. No colour discernible. Averted vision not required. I estimate
northerly component to be the brighter, so this would put PA at 150 degrees
or so. In fact, 33 Doubles lists this as PA 3 degrees, so I guess the southerly
component must be the brighter. SMP numbers agree (S component: 7.35, N
component: 7.31, putting them I think at 4% difference in brightness: no
wonder I couldn't tell them apart!).
OSS 181 in Lyra
Date & Time: 18 August, 2001, 00.45
Seeing: 5 <1-10 Seeing Scale (10 best)>.
Location of site: Annen, The Netherlands - 53N, 6E
Site classification: Village backyard
Sky darkness: 4.5 <Limiting magnitude>
Bino: Leica 10x42 Trinovid, semi-handheld
|Seen and split, but a bit faint. OSS 181
is in very good company because on the edge of the same FOV we can see
the bright and beautiful Albireo. The bright and wide double Alpha Vul
can also be seen in this field.
