WATEC 902H + FD 1.8/50 mm + TANGRA astrometric software, UCAC-4 star

Slightly hazy sky but nevertheless could observe USA 276 well. Data are from two
consecutive passes, 01:30 and 3:06 local time (23:30 and 01:06 UT). Saw the ISS
twice too.

During the first pass USA 276 was faint (mag +5 to +6) and was not visible by
the naked eye. During the second pass it was brighter, max +3 around
culmination, and I could see it with the naked eye.

Used a 1.8/50mm lens on the WATEC this time, not the 1.4/85mm.

I also photographed, with a Canon and 35 mm lens (first pass) and 50 mm lens
(second pass). Obtained some nice pictures, especially on the 2nd pass.
