Telescope: AP 155 F/7 Apochromat
Magnification: 214X, 343X, 429X
White. tough pair. Suspected at 214X, seen with 10mm (343X). Best view with 16mm plus 2X Barlow (429X).Secondary seems significantly fainter.

Seeing: Varying from 3 to 5 <1-10 Seeing Scale (10 best)>
Transparncy: 7 to 8 <1-10 Seeing Scale (10 best)>
Location of site: Annen, The Netherlands (53N, 6E)
Site classification: Village backyard 
Sky darkness: ~5 <Limiting magnitude>
Telescope: Celestron C11 
Magnification: 187x, 280x 
Harshaw Scale: 4 <1-5; 1 best> 
This pair could be seen as elongated at 187x and very elongated at 280x with a vaque separation on short moments. The unsteady sky made the starimages very fuzzy.
This elongated fuzziness showed a yellow color.

Very tight, I was only able to get a slight elongation on this. The color appeared white to me.

Seeing: 3 <1-10 Seeing Scale (10 best)>
Transparency: 7 <1-10 Seeing Scale (10 best)>
Location of site: Charminster, Bournemouth, Dorset
51ºN, 1ºW
Site classification: Suburban
Sky darkness: 4.3 <Limiting magnitude>
Moon: 4 Days Old, but below horizon
Bootle Scale: 8 (Suburban/Urban)
Telescope: 8" Meade LX-90 SCT f/10 (Lucy)
Eyepieces: 30mm Celestron Ultima (67x), 
26mm Meade Super Plossl (77x), 
12.5mm Celestron Ultima (160x), 
2x Barlow
Magnification used: 67x, 160x, 320x
     
Obscenely tight and I didn't achieve a clean split. In the same FoV at 67x as the very bright (through the eyepiece) orange star Nu Pegasi. No sign of duplicity at 60x, and only just elongates at 160x.
 
Going up to 320x only produces a figure-of-eight, and the seeing isn't that good at this magnification. I not surprised, I couldn't split it properly as it has a listed separation of only 1.2 arcseconds!
