Date & Time: November 09, 2001 Seeing: 3 <1-10 Seeing Scale (10 best)> Transparancy: 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> Telescope: Guan Sheng 80mm f/6, Celestron C11 Magnification: 19x, 93x Harshaw Scale: 2 <1-5; 1 best> |
A nice and bright pair for the 80mm as well as for the C11. A good split with the 80mm at 19x. With the C11 I needed some study on the colors. A first mpression of yellow and purple/blue looked somewhat strange. I ended up establishing the colors as white and yellow | |||

Star colors: primary almond;
secondary bluish shades
Comments and observations: An elongated airy disk in the finder revealed itself as another beautiful and colorful pair at 18x+. Similiar in coloration to Struve 534 but the primary showed stronger orange tones.

Date & Time: Monday, December 10th, 2001 10 p.m local; UT +10 Seeing: 6 <1-10 Seeing Scale (10 best)> Transparancy: 9 <1-10 Seeing Scale (10 best)> Location of site: Terara, New South Wales, Australia, Long.150º.38 ; Dec. S 34º.52. Site classification: Suburban Conditions: No Moon Temp. 17ºC. Sky darkness: --- <Limiting magnitude> Telescope: 8" Newt.

This double is immediately
NW of STF 534 and is readily found.
Comments: At low power this
is a Bluish White primary with a Deep
Also observed: Phi Tau(52):
Ambience: I had almost forgotten
what a clear, dark sky looked like. Tonight after rain and storm and the
movement of the season from late Spring to mid-Summer and through
two circuits of the Moon, there at last was the glittering
void: crisp, pristine and eternal. Even in binoculars the now fully-risen
Megellanic Clouds yielded clusters of Globulars and bright nebula. The
Milky way spread richly from the fully-risen Orion all the way South to
the Southern Cross, now low beneath the pole. It was one of those nights
when simple

Date & Time: 10 December 2001, 20:50UT. Seeing: 6/5 <1-10 Seeing Scale (10 best)> Location of site: Northwich, Cheshire. UK. (53° 15' N -2º 33' W). Site classification: Suburban Moon Phase: Sky darkness: 3.0 (UMi) <Limiting magnitude> Conditions: Cold with drifting mist, frosty. Telescope: 200mm f/6 Newtonian reflector Mount: Vixen GP Eyepiece(s): 20mm and 10mm Plossl, 6mm UO orthoscopic, Celestron MicroGuide with Barlow. Magnification: X60, X120, X200, X322. |
Using X60 on this pair I
observed a pale yellow coloured primary with a purple or blue companion.
With a magnification of X200 the colours seemed to be pale yellow and purple
for the companion at an estimated PA of about 30Deg. The colour contrast
improved using X120, the best view, but I
couldn’t decide if the companion was blue or purple. Perhaps a darker sky is needed for this one!

Back to wider pairs. This
one apprears as a brillant blue-white primary with a sojmewhat fainter
and deeper blue secondary. PA estimated at about 30d. They form the peak
of a triangular asterism with 2 other fainter stars.
