Star: 5 Lyncis A-C
Date & Time: 04/03/2004, 22:00 LT
Seeing: 3 <1-10 Seeing Scale (10 best)>
Transparency: 
Location of site: Annen, The Netherlands, 53N 6E
Site classification: Village backyard
Conditions: Almost Full Moon in Cancer
Temperature: 0°C
Sky darkness: 3.5 <Limiting magnitude> 
Telescope: MK67 (150mm f/12 MCT)
Eyepieces: 
Magnification: 45x		 A very wide and easy double. The color of the primary is stunning and makes the pair worth observing, it's like bright, shiny copper.
This pair is also in the Binocular doubles project and I suppose it's an attractive target for bino's.
There should be a B-component of magn. 12 at 30". But that's totally invisible with my MK67 under these circumstances.

Ambience: Believe it of not, but yesterday-evening I was able to observe some doubles!
The lazy Sky-cat was comfortably stretched out along the firmament, almost hidden by the strong Moonlight. But the sky was clear and with a bit of cat-hopping some precious jewels were revealed in it's fur. My own cat, Jimmy, didn't mind me fooling around with his Sky-companion. Very sensible as he is, he stayed inside, comfortably curled up on a warm spot.
The temperature was around 0° C and there was a strong southerly wind. Seeing was terrible, as can be expected under these circumstances. My MK67, which always stands ready for a quick hop into the backyard didn't need to cool down, the star-images were terrible anyway.

Location of site: Texas, USA
Site classification: Suburban
Conditions: full moon 
Sky darkness: 2.5-3 <Limiting magnitude> 
Telescope: C8
Eyepieces: 25mm, 17mm, and 10 mm 
Magnification: 		 "The fog comes
on little cat feet
it sits looking
over harbor and city
on silent haunches
and then moves on"
Carl Sandburg

This opening line from Carl Sandburg's poem "The Fog"* seems rather 
appropriate for my session last night. 

A very wide pair, also rather pretty. The primary was 
strong yellow, perhaps even orange; in contrast the secondary, located 
almost exactly due west, seemed blue. I imaged this with my SAC-IV, and 
used these to measure the Separation at 100.2 at PA 266.7.

Ambience: My cat remained aloof, as well befits a cat, and the dog was content to sleep in the grass in the upper part of the yard.

Location of site: Northern Kansas City,

980 ft above Mean Sea Level
Site classification: suburban
Conditions: 
Sky darkness:   <Limiting magnitude> 
Telescope: Celestron C-11
Eyepieces: 
Magnification: 98x
Rating Scale: 4E <1 to 5 (1 being outstanding
view, to 5, a dismal view) and letter E, M or D (easy, moderate or difficult)>		 At 98x, colors of R and W.  The only redeeming thing about the view is the placement in the field of the bright stars SAO 25717 and SAO 25719.  Did anyone catch B lurking at 31" @ 140?  It is listed at 9.8 magnitude, but I think that is highly overstated.

A scale model has the primary as an enormous star (about 53.5 inches or 136 cm in diameter-the size of a weather balloon), with the C star lying way out there at 101 miles (163 km).  B, by the way, would lie 33 miles (53 km) away.

Star: 5 Lyncis A-C
Date & Time: Mar.15, 2004, 8:30 to 11:00 local time
Seeing: 6 <1-10 Seeing Scale (10 best)>
Transparency: Average to poor
Location of site: Barreras, Salamanca, Spain
Site classification: Rural
Conditions: Temp. 10º
Sky darkness: no moon <Limiting magnitude> 
Telescope: Celestron 9.25" SCT
Eyepieces: none
Additional: DX-8263SL video camera with 2.5 Telemate.
 
 This is the widest pair in the list and I was just able to get the two components in the field of view using the 2.5 power mate. Afterwards I noted that the B component was out of the field so could not measure the AB pair. I did not want to remove the powermate in mid stream so I just measured the AC pair. Both white. Sep. 95.8" and PA 272.4º.
 
Ambience: Although the seeing was marginal the night was very springlike and quiet. The small frogs in a nearby pond were all in fine voice acting like a choir from an opera. It was a good night to get out under the stars.
