I believe that Mu-1 was
a joke from Luis... so I reduce the count in one
and believe that this program needs other star of other name.... like "32" Doubles in Bootes ;-). Well, jokes apart, the complex
of Mu-1 and Mu-2 Bootes was a beautiful
After this first official
"33" night I was very positively motivated for

2 Bootis (STF 1938 BC)
Date & Time: May 07 2001 Seeing: 6 <1-10 Seeing Scale (10 best)>. Location of site: Annen, The Netherlands (53ºN, 6ºE) Site classification: Village backyard Sky darkness: 3.5 (UMI) <Limiting magnitude> Sky : Full Moon in Libra and a slight haze Telescope: Meade LX10 (8" f/10 SCT) Magnification: 100x, 200x Harschaw's Scale: 3 <1 to 5> |
By the time of observing
this one, at the end of this nights session, hazyness increased and the
optics started to dew up. Because of this Mu-2 gave a bit of trouble; needed
100x to be just seperated. With 200x however clear and obvious separation
was achieved. With better conditions this could well be a beautiful bright
and close system.

Date & Time: Seeing: 6 <1-10 Seeing Scale (10 best)>. Location of site: Near Halifax, West Yorkshire, England Site classification: suburban Sky darkness: 3.0 (UMi) (Full Moon) <Limiting magnitude> Temperature: 3ºC Telescope: GX 250 10" Newtonian Eyepiece: 20 mm Plossl, 12.5 mm Plossl, 9 mm Ortho, 7.5mm Plossl,. x2 Barlow. Magnification: 60x, 97x, 133x, 160x, 266x |
Some distortion seen at
x 97 and split in moments of better seeing at x133. Needed x160 to obtain
a clean split. The best view was at x266 showing two nicely separated deep
yellow stars.

Mu-1 one was even split in the mis-aligned binocs I was using :) The primary looked kinda bluish in my 15mm (100x), at that magnification I was also able to split Mu-2 into two clear components. | |||

Mu 2 Bootis
Date & Time: 12 May 2001 ( 23:45 UT ) Seeing: 5-6 <1-10 Seeing Scale (10 best)>. Location of site: Cheshire. UK 53° 15' N -2º 33' W Site classification: Suburban Sky darkness: 4.3 (UMi) <Limiting magnitude> Conditions: Nice clear night, looking good. Telescope: 200mm f/6 Newtonian mounted over a Vixen GP mount (manual slow motion). Eyepieces: 20mm plossl, 9mm, 6mm UO orthoscopics. Magnification: X60, X133, X200 |
Using X60 I could detect elongation for this double and needed to use X133 to see a very close pair of pale yellow stars. Increasing the magnification to X200 gave the best view of a beautiful pair of yellow stars, cleanly separated. The PA of the pair was estimated to be on the 10-190deg line. | |||

Just split at 83X, but best
at 143X. A near equal pair of eyes one salmon and one white.
