Seeing: 5/10 at best
Transparency: fair
Location of site: Mattawa WA, USA 46N 119W
Site classification: rural
Conditions: temp 48F, dry no wind
Sky darkness: limiting mag 6.5
Telescope: Meade 16 LX200GPS
Eyepieces: not used
Imaging: DX8263SL video camera at prime focus
Magnification: app. 600x

 Viewed many times before, a nice pair of contrasting colors, yellow and blue. Poor split, as seeing caused the images to merge and the double and event triple at times. Measurement; 2.6 sec at 165.7 deg PA.

Seeing: 7 out of 10
Transparency:  out of 10
Location of site: 4433N 0012W 
Site classification: Rural
Conditions:
Sky darkness: limiting mag = 6
Telescope:
- visual : 120mm refractor used as guidescope 
- imaging : homemade Newton 8", Barlow 3x with tube extender, Audine K400 (sampling 0"32/px) 
Eyepieces: 20mm,7.5mm 
Reductions: Reduc V3.49

easily seen as double in the refractor with the 20mm , a great view with the 7.5mm. Measure : 166°3 / 2"66. Exposure time was too long and the components overlap, to be re-observed.
 
Nov 6th measurement is 163°9 / 2"75

Time: 20:25 UT
Seeing: 7 out of 10
Transparency: 9 out of 10
Location of site: Küssaberg-Dangstetten
Germany / 47°36, 8°21
Site classification: Rural
Conditions: no wind, high humidity
Sky darkness: better than 5mag
Telescope: Celestron 8
Eyepieces: 26mm Plössel
Diagonal: Yes
Magnification: 77x

 Could be just split with 26mm Plössel. No problem with the 12mm RKE. A bit more complicated than Struve 300.

Star: Struve 174
Date & Time: 30 October 2005
Time: 3:05 UTC
Seeing: Pickering 4
Transparency: Average
Location: New London Township,
PA, US (+39d45m,-75d52m)
Site classification: Suburban/Rural
Conditions: Clear with passing clouds
Sky darkness: Not determined
Telescope: TMB152 f/7.9 Apochromatic Refractor
Mount: Losmandy G-11
Eyepieces: TMB Super Monocentric 14mm, 8mm, 5mm
Magnification: 86x, 150x, 240x

 The star seemed double at 86x, but I could not be sure. At 150x, however, it was resolved into a yellow and blue pair. The seeing did make the split come and go. At 240x the pair was easy in the moments of the best seeing. The colors remain yellow and blue to my eye.

Seeing: 7/10
Transparency: 8/10
Location of site: Terara, New South Wales,
Australia, Long.150º.38 ; Dec. S 34º.52
Site classification: rural
Conditions: Temp. 18ºC
Sky darkness: limiting mag 6.5
Telescope: 8" Newt. F9
Eyepieces: 25mm K, 12.5 mm Ortho
Magnification: app. 600x
Harshaw Scale 1-5: 1 best

 A yellow and bluish pair just split with medium eyepiece. A faint star south in the field. HS2

I have never been happy with the Heavenly Ram and it was only when I read that it was once known as Gam the Scimitar, by the ancient Euphratean astronomers that this constellation started to make sense. The stars, Alpha, Beta and Gamma easily suggest the raised sword to me from where I watch so far south as it fills a fairly dull area of northern sky before the arrival of Taurus and Orion.
