Star: Burnham 65
Date & Time: 2 September 2004, 23.00 LT
Seeing: 8 <1-10 Seeing Scale (10 best)>
Transparency: 4 <1 worst - 10 best>
Location of site: Annen, The Netherlands
53ºN, 6ºE
Site classification: Village backyard
Sky darkness: 3 <Limiting magnitude>
Conditions: bright moon low in the southeast
Telescope: Celestron C11
Eyepieces: Plossl 10mm, LV 7mm
Magnification: 280x, 400x

 

 The DI of 97 of this pair indicates it to be somewhat more difficult ot split than STF 2723 (DI 94). This because of the greater difference in brightness. In my case, using the C11, this was not true. BU 65 can be described as a nice and easy pair. No problem with 280x and actually a real pretty pair at 400x.

 another one not cleanly split, lumpy, but not even enough to call it a peanut

Telescope: C11, Televue-85
Eyepieces: 20mm

Foiled at all powers and with both scopes over several evenings.  This one has got my number.  Will have to try with 8.5” refractor on a better evening.

Transparency: poorLocation of site: Silverdale WA, USA
47N 123W
Site classification: suburb-rural
Conditions: temp 55F, damp. Bright moon
Sky darkness: 4 <Limiting magnitude> 
Telescope: Celestron C8
Eyepieces: DX-8263SL color video camera at prime focus, 3x and 6x
Magnification: app. 350x,1000x,2000x

    		Real difficult due to the poor seeing and magnitude difference. Secondary is just a faint blob. Measurement 1.4 sec at 207.5 deg PA with uncertainty of 0.2 sec and 7 degrees.
