Message: <blockquote data-quote="Binastro" data-source="post: 3531955" data-attributes="member: 111403">Henry,Quick test cotton reel round end 34mm diam at about 5m.Squashed like Swaro 8x32 SV but not as bad perhaps half as squashed as end picture.But out of focus like 8x56 FL end picture.No false colour noted in room light not very bright.The out of focus edge image can be partly refocused.Rather more out of focus edges than I remember from distant targets unless my pupil size might be big?Not used to close targets.I don't want to get migraine aura messing around with bright lights so will try another day if suitable.P.S.Distance binocular to cotton reel target 5.1m Leica Disto.Illumination 2 60W tungsten pearl candle bulbs at about 10ft not measured.Illumination of target rather dim.Cotton reel base ~3.05 degrees AFOV (8x assumed).</blockquote>
