Albeiro
This double star marks the head of Cygnus, the
swan.
You need steady hands or a tripod to split it with 50mm binoculars and
I don’t split it every time. Bigger binoculars or a telescope are
better.
Many observers claim that Albeiro is the most
beautiful
double star because of the colour contrast between the orange primary
and
the blue (some say green) secondary. I don’t dispute it.
Albeiro is at RA 19h 30.7m Dec +27 deg 58 min.
Albeiro is visible from midnight in late March
until
just after sunset in February.
