21 + 22 Tauri
Date & Time: 2000/11/13 (00:10UT) Seeing: -- <1-10 Seeing Scale (10 best)>. Location of site: Chester, England (53 11 08N; 02 51 39W) Site classification: Suburban Sky darkness: Moon just past full. Conditions: Cold, mainly clear. Binocular: 8 x 30W Zeiss Jenoptem binocular (hand-held) |
A delicate pair in the Pleiades (probably the
best binocular field
in the sky!). I suspected a bluish hue to each star, but I may
have
been unconsciously influenced by the brighter stars in the field, which
I always see as blue-white. Surprisingly faint pair, but the Moon
is close by.

Date & Time: November 15, 2000, 2:15 UTC Seeing: 8 <1-10 Seeing Scale (10 best)> Location of site: Pflugerville, Texas, USA (30 degrees N.) Site classification: Suburban Sky darkness: -- <Limiting magnitude> Conditions: Clear - Better than average. Temperature: 44° F. Binocular: Orion 8x42 (handheld & mounted)

Part of M45 (the Pleiades).
Fairly easy even hand holding
the 8x42s but much more attractive when the binoculars are
mounted.

Known as Asterope, lie just
below(for me) the triangle
of 16,19 and 20 Tau. Their wide separation of 168" makes them reachable
with the naked eye were it not for the misty haze of their
companions.
While my 7X35 Russian-made Tentos reveled both
stars clearly, the Somet
25X100 showed the marked colour difference of the 5.6 mag. Tau 21 as
Whitish
yellow and the fainter Tau 22 of 6.4mag as Whitish blue. Their
light
shimmers as through clouded gauze.

Date & Time: 0935 UTC, 11/28/00 Seeing: 6 <1-10 Seeing Scale (10 best)> Location of site: Lake Oswego, Oregon Site classification: Suburban Sky darkness: 4 <Limiting magnitude> Temp: cold Binocular: 7x50 Nikon (hand held) |
The double 21+22 Tau is located
on the northwestern edge
of the Pleiades, one of the great objects to view through
binoculars.
I was very lucky to observe this double tonight. At mag 5.6/6.4
the
double was very, very dim and intermitant. Separation was about half
that
of 27+BU.
Viewing through a high haze and against a significant light bubble, Eta Tau with it's mag 8 companions was simply out of the question tonight. The Pleiades is one of my favorites and I always enjoy poking around. They always look to me like someone took a handful of diamonds and threw them out on black velvet. This fall I identified a dozen doubles in or near the Pleiades to observe as a personal project. The doubles arn't all that impressive but I enjoy running my fingers through the diamonds. Very brisk this morning. You didn't want
to stay out too long
but a little while is very nice. The ever present Portland light
bubble makes the sky look like cottage cheese but at this hour
most
of the neighbors have turned off their monster porch lights. Winter
has

Date & Time: 29/12/00 21.35 UT +10h Seeing: 6, improving <1-10 Seeing Scale (10 best)> Location of site: Sydney, Australia Site classification: Suburban Sky darkness: 4.69 improving to 5.37 <Limiting magnitude> Binocular: 7 x 50 binocs |
Easy split however required
averted vision to detect both
components. Found at the base of a christmas tree asterism. Would be
seen
as an inverted V by northern observers.

Date & Time: 1-17-01, 3:30 - 5:30 UT Seeing: 4~5 <1-10 Seeing Scale (10 best)> Weather: clear, but quite chilly at 45°F (Hey, it's cold to us....)

Both were fainter than the brighter stars in
this cluster.
Both have a blue tinge to them, but the comp. is the stronger tint of the 2. PA near 310°. |
