Site Classification: Suburban 
Sky darkness: 4.5-5.5 <Limiting magnitude> 
Instrument: 8" F9 Dobsonian.

 		 This is a rich yellow star with a faint delicate companion of unknown colour following in the field at X144 magnification. An interesting deep blue star is found south in the field. 

Ambience: a very clammy night with swirling mist and dewing up additing a glow to distant street lights. I was glad to have wheels on my telescope to chase these low objects that hid behind chimneys and rooves. A visiting son turned on all outside lights to make a snack in the kitchen(?) so this was a sign to take my damp feet indoors.

Star: 52 Cygnus 
Date & Time: 19 August 2000 (2300) 
Seeing: 6 <1-10 Seeing Scale (10 best)>. 
Location of site: Chester, England (53 11 08N; 02 51 39W) 
Site classification: Suburban  
Sky darkness: 4.5 <Limiting magnitude> 
Telescope: 63mm Zeiss Telementor refractor 
Magnification: x84, x140, x210 and x280 
  
 		 An extremely frustrating star!  I suspected the comes at all powers except x280.  I most strongly suspected/glimpsed it x140.  I feel almost certain I saw, or at least repeatedly glimpsed the companion, but I cannot say I am 100% sure of it.  Unfortunately, the seeing has slightly deteriorated since my earlier observations tonight.
