Cygnus was high in the skies and well above the trees and our house. Used the go-to to get to Deneb from M29 (just viewed). From there, I slewed E-NE using my 25mm eyepiece. Once M39 was found and centred, I switched to the 12mm eyepiece for more detail. The centre stars seemed to form a semi-circle of brightness; otherwise, not many stars appear in this cluster. There was a hint of a very, very pale background of stars that may have been the Milky Way or due to a transparency challenge.
