Seeing: 4->2 <1-10 Seeing Scale (10 best)>
Transparency: 4 <1 worst - 10 best>
Location of site: Sibiciu de Sus / Buzau county ROMANIA.  45.333 N / 26.350 E / Elevation 264 m
Site classification: Rural
Conditions
:
around 17C at the begining but going considerably low at the end (about 10) / no wind at start but low-medium speed and intermitent wind at the end of session
Moon: 98% low altidude
Sky darkness: 3.4 <Limiting magnitude>
Telescope: 10" F/5 dobsonian reflector
Eyepieces: Eyepieces 25mm Sirius Plosll / 10mm Sirius Plosll / 3x achromat Barlow
Magnification
:
50x , 125x , 375x
  
50x no companion at all at this magnification, 125x companion can be seen but very close, still if paying enough attention it can be clearly splited but there is a considerable magnitude diffrence between components. I estimate it around 2-3 magnitudes The main star seem to have a slightly blue color 375x The split is more easy and clear but the magnitude diffrence and small distance between components stil put some little problems at first sight. Eye estimation done PA - around 70-80 SEP arround 3-4
