20cm f/6 Newtonian, Cave Astrola @ 76x
Seeing: 5 Transparency: 6 Moon: 0%

A large cluster of bright stars best appreciated in the 40mm finder, a straight line of six 6th to 7th magnitude evenly spaced stars spanning 1.5° east to west with three additional bright stars to the south at the midpoint of the line, the apperance is truly fitting of The Coathanger appellation, 4 Vul, 5 Vul, and 7 Vul are all found among the brighter stars in this group, in the 8" 'scope the view is also quite impressive, at the center near 5 Vul one greets a field full of 5th to 7th magnitude stars

Seeing: 6 Transparency: 5 Moon: 43%

Easily found while sweeping the general area, a straight line of six 6th magnitude stars spanning about 2° with three more 5th magnitude just to the south forming the hook, the group truly appears like the eponymous coathanger
