Original report by Robert Toop: https://bugs.launchpad.net/stellarium/+bug/1299412

The position angle for 61 Cyg A to B appears to be 90 degrees; should be 152 degrees.
The separation appears to be 48 arcsec; should be 31.5 arcsec.
Good news is that cranking back the clock in Stellarium 0.12.4 shows proper motion that matches 1916 & 1948 photos in "Burnham's Celestial Handbook."

I love this program, but until now I assumed ALL star positions were based on Hipparchos satellite. Is there a problem with close doubles in general?
