Star: Struve 65
Date & Time: 4 July 2003, 1:00 AM PDT
Seeing: 5-6 <1-10 Seeing Scale (10 best)>. 
Transparency:  OK to good
Location of site: Larch Mountain, OR, USA
Site classification: rural, (4,000 ft elevation)
Temperature
Sky darkness: 5.5 <Limiting magnitude> 
Conditions: Cool, slight dew
Telescope: Takahashi 102mm, Perspicillum
Eyepieces: 7mm UO ortho
Magnification: app. 117x
Decided to try one last semi-easy one before I packed up. The sky conditions and the dimness of the star prevented my from going any higher than 117x, but it was cleanly split at that. This is an example of a delicate white pair that I enjoy just as much as many of the colorful ones. It seems you are catching this lovely, petite couple in some dark corner out of view from the general traffic.

9mm, 5mm

Good black separation at 147x... the almost identical magnitudes make this a very nice pair.

Date: 28, July, 2003 , 23:45 -> 2:45 local time
Location of Site: Sena de Luna, Spain
42.55N, 05.57W
Seeing: 6/7 <1-10 Seeing scale (10 best)>
Transparency: 6 -> 5 <1-10 scale (10 best)>
Other conditions: No Moon. 
Temperature:16ºC
Altitude: 1,200 mts (3,940 ft)
Site classification: Rural
Sky darkness: about 5.5
Telescope: Takahashi FS-102
Mount: Vixen GP + Skysensor 2000
Eyepieces: 9mm Nagler, 5mm and 3.8mm Eudiascopics
Diagonal: Zeiss prism diagonal
Magnifications: 91x, 164x, 215x
 
With the 9mm Nagler, both components appear as, more or less, the same magnitude. Under this seeing and this eyepiece, there are moments where the split is clear, and other moments when it’s unsplittable. A rather easy double.
   
The field at this magnification is not specially rich and I would rate this double as a 3 star one. Both components with the same color: yellowish-orangeish. With good seeing and transparency, this would be a beautiful double.
