Date & Time: July 8-9 2003 Seeing: 6 [see http://www.backyard-astro.com/Logs/logsreport.html Transparency: 3/10 Location of site: 45°N // Tomahawk WI, USA Site classification: Rural Temperature: 65°F dropping to 50°F Sky darkness: 4/10 (Thompson Scale) Conditions: surprisingly minimal dew; slight breeze from the North Telescope: Meade 8" f/10 LX-10 (Snoopy ) Eyepieces: 32mm, 13.8mm, 9mm, 5mm Magnification: 63x, 147x, 226x, 406x |
Here's another stretch of
the imagination: the four bright stars at either
end of the 63x fov surrounding this double appeared to be a miniature Gemini, with our target stars waist-high and kicked a bit to the left. Nicely split at 63x, the 'A' star carried an orange tint with the 'B' star appearing to be a very light blue, but might appear so only by comparison.

Easy to see, a bit faint
and with noticeable difference of magnitude. No color is perceived. The
field is very interesting because not far from it, there is another double
(very nice), making the field very interesting with the 9mm Nagler. Moreover
this seems not only a double but a multiple system, with a total of 3 or
even 4 components (transparency doesn’t allow me to determine exactly).
A rather open multiple system. With a bigger telescope, I bet this would
be a nice show.
