Description:
Primary is large, yellow-orange. Secondary is substantially smaller and quite
blue. Under low power, I am just able to relove the pair. Under high power,
separation, size and color differences are pronounced. Watson (author of an
observing guide I own) says the blue star is actually a triple in itself. A
good resolution test for an 8" is to resolve the blue into two components of
equal magnitude. I was unable to do so with my 10". A bit of a breeze was
present which unsteadied the scope a little. A very pretty multiple. As nice
or nicer than Alberio.
