Struve 1788 -- Quadruple Star System in Virgo
A Quadruple Star in Virgo
The Struve 1788 Star System is dominated by a pair of two yellow-blazing stars.  With a
separation of only 3.4 arcseconds, high power is helpful in separating them.  The other
two stars in this star system are further away and dimmer.  Both appeared white to me.  
The foursome makes a pleasing sight.
