Star:  Herschel 1957
Date & Time: 2 Nov 2003 9:30pm to midnight
Seeing: 2-3  <1-10 Seeing Scale (10 best)>. 
Transparency: poor
Location of site: Silverdale WA, USA
47N 123W
Site classification: suburb-rural
Conditions: temp 30-35F, dry
Sky darkness: 4.0 due  moon <Limiting magnitude> 
Telescope: Celestron C8
Eyepieces: DX-8263SL video camera at prime focus 
Magnification: app. 333x		 A brighter primary easier to locate in the moonlight. Secondary is quite a bit fainter and blue; primary creamy white. The WDS lists the secondary as a very close pair at 0.1 sec, need 48 incher here!  Measurement; 6.48 sec at 024.8 deg PA

Star:  Herschel 1957
Date & Time: November, 19th  2003
10.30-12 mid-night local; UT +10
Seeing: 7 <1-10 Seeing Scale (10 best)>. 
Transparency: 8 <1-10 Scale (10 best)>
Location of site: Terara, New South Wales
Australia, Long.150.38 ; Lat  -34.52. 
Site classification: suburb-rural
Conditions: Temp 16° No Moon
Sky darkness: <Limiting magnitude> 
Telescope: 8" F9 Newtonian. Eyepieces
Eyepieces: 16mm and 12mm Ortho
Magnification: 
Harshaw Scale: 5 <1-5, 1 best>		 Mag. 7.4/9.1; Sep. 6.1. 
This is a challenging(for that read extremely difficult!) object to locate in a confetti of dim stars SW of Beta Ceti. The eyepiece field was strangely empty which helped in spotting the very dim companion, just glimpsed wide.

Site classification: suburban
Conditions: Cool, 44°F, 7°C. Crescent moon  
Sky darkness:  4 <Limiting magnitude> 
Telescope: C8
Eyepieces: 25mm, 17mm, and 10mm eyepieces
Magnification: 		 A fairly bright primary with the secondary appearing as a small dot just off the primary on the NW side. Estimated PA 30°. Appears as part of a triangular asterism with 2 other stars. The primary appeared white, with perhaps a tinge of yellow.

Star:  Herschel 1957
Date & Time: 25:10:03 20:00 local time
Seeing: 8 <1-10 Seeing Scale (10 best)>. 
Transparency:  Good
Location of site: Barreras, Salamanca, Spain
Site classification: Rural
Conditions: Temp. 10ºC, calm
Sky darkness: 8 <Limiting magnitude> 
Telescope: Celestron 9.25" SCT
Eyepieces: none
Additional: Stella Cam Ex video camera, prime focus
Magnification: 		 The video camera is black and white so no color can be noted. This double consists of two components almost two magnitudes in difference and it was readily noted on the screen. Closer split noted on laptop screen. Theta = 25.4º and rho = 6.34"
