Date & Time: November 18, 2000, 00:00 MET Seeing: --- <1-10 Seeing Scale (10 best)> Location of site: Annen, The Netherlands (53 N, 6 E) Site classification: Village-backyard Sky darkness: 4 <Limiting magnitude> Conditions: Some clouds Temperature: 5ºC Binocular: Swift Supreme 10x50 (on tripod) |
A very wide pair which wouldn't
be very interessting if
they didn't sit in the beautiful starfield of Orion's Sword.
The distance of the stars, given by the Hipparcos is 1165 ly for 42 and 473 ly for 45. If this is right then there are obvious no real double. We can see another star in between 42 and 45 (V359 Ori - mag. 7.3). The three of them form just an asterism I think. In the same FOV we see, beside the nebulous
glow of M42, several other
doubles :

Date & Time: Dec 5th 2000. 10 -11p.m local; UT +11 Seeing: 5-6 <1-10 Seeing Scale (10 best)> Transparency: 6/10 Temperature: 18ºC Other Conditions: Calm. Moon 9 days old Location of Site: Terara, New South Wales Australia, S34.52, W150.38 degrees. Site Classification: Suburban Sky darkness: North 4; South 4.5 <Limiting magnitude> Binoculars: 7X35 Tento. 25X100 Somet. (Occasional 16" Dob comparisons ) HS: 2 HS= Harshaw Scale1-5 (1 best) |
The splendid tour continues. We
now jump to the Northern
tip of the Sword to visit a very wide pair of mag. 4.7 and 5.3. I
recorded
the colours as Pearly white and Deep yellow. Comments. While not as
impressive
as Struve 747, the faint stars embedded in the field make a striking
field,
even in poor seeing.

| Star:
42+45 Orion
Date & Time: Tuesday, 9th, January, 2000, 21:15 UT Site of Observation: Alto del Naranco, Oviedo Site Clasification: Suburban Seeing: 2-3 <1-10 Seeing Scale (10 best)> Sky darkness: About 3 <Limiting magnitude> Transparency: 6 Temperature: About 11ºC Conditions: Very strong wind (maybe about 40 km/h) Binoculars: Pentax PCF-V 8x40, 6.3º field. Tripod mounted. |
This "double-double" (in good
telescopes) is really easy
to locate between the complex NGC 1981 (south from) and M42-M43 (north
from). Both stars appear to have the same blueish coloration and this
has
been the "first double-splitting light" for my new Pentax
binoculars.
Anyway, the strong wind and bad seeing makes
the observation not as
enjoyable as it could be. I proceed to make a quick trip in Orion
visiting
Betelgeuse, Meissa, Bellatrix, Rigel, Saiph, Alnitak, Alnilam and
Mintaka
(all the belt in the same glorious field of view), Sigma, again 42+45
and
Theta1, Theta2, but I can't make more splittings due to the bad seeing.
Even Mintaka was imposible to split.

Date & Time: UT 11th Jan 2001 18:00 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 FOV: 5d |
Easy to locate, directly beneath NGC1981 in
the binocular FOV. Distinctive
shape of NGC1981's prominent stars gives 42 and 45 Ori away. Wide
separation
of 42 and 45, with 42 being slightly more yellowish in colour than 45,
and somewhat brighter.
A third, much fainter, star was visible forming a small triange with 45 and 42. This star is V359 Ori (SMP mag. 7.3). Local conditions can be sensed by the fact that about 8 stars in NGC1981 could be seen. 42 and 45 Ori were rather low in the sky during this observation (17 degrees) - perhaps more stars in NGC1981 would be visible later in the evening. Estimated PA 90 degrees.
