CYGLX : forms close double with 13.8, the AAVSO-chart shows a third star on
a line with LX and 13.8. It does not exist, there is a 15th magnitude star
which forms a small triangle with them. This was confirmed after examining the
POSS-plate here at the Kapteyn Institute.
There is also a chart-error : observers should take care when LX becomes 
fainter !!
