Open Cluster in Cygnus
NGC 6913
Mag 7.1
Cooling Tower Cluster

Obvious why it got it's name!

In a very rich starfield, seven stars all appear as same magnitude

The Cooling Tower
Visible tonight in finderscope, it is so clear
Rather ragged in 12mm, the brightest eight stars, of Mags 8 and 9 do indeed form an asterism which looks like a cooling tower
