The Caldwell Objects

At a glance the two stars at the cluster's heart are
easy doubles, and the western double has a
fainter companion to the southeast, making it a
triple. Between these southern and central star
pairs is another nice pair of equally bright suns
oriented west-northwest and east-southeast.
Barbara Wilson notes that with a 13.1-inch f/4.5
telescope at an altitude of 7,200 feet
49 & 50
she could detect numerous faint suns encased in
the nebulosity at 47x. The challenge I see,
however, is for someone to detect the faint star
that Albert Marth detected within a knot of
nebulosity. Although he used a 48-inch telescope,
I suspect the star is visible in much smaller
instruments. Yet I know of no one repeating this
remarkable feat.
