50x very wide pair Stars
seems identical No color 125x one is just a little
more bright The mag
diffrence seems very small ( about a few 0.1 mags probabily) It can be
seen a
second companion , pretty weak as magnitude and quite close from the A
component. The companion is evident with averted vision but little
difficult
with direct vision (probably because the magnitude diffrence) 375x The second companion
is now clearly seen and clearly splited There are
about 3-4 magnitude diffrence to the second companion The SEP between
AC is
about 1/5 from AB SEP The SEP of AB is about 1/4 of the field . Rough
estimations SEP AB ~ 95 arcsec PA AB ~ 40 degrees / SEP AC ~ 19 arcsec
PA
AC~280 degrees NOTE: The above estimations are quite rough , and made with only eye aproximations. |
