NGC6933 (**)

Image source: DSS II (blue) - 5×5'
Name: NGC6933
Type: **
Constellation: Del
Coordinates: 20h33m38.50s / +07°23'25.00"
Components: v10.8 mag / v12.5 mag / 30.0" / 215.0° / -
I guess it is just an optical double star. At least I could not find any entry in the 'Washington Double Star Catalog' (WDS). Located west of the globular cluster NGC6935 in an angular distance of less than 10 arcminutes.

8" f/6, 80x, Bortle 4, NELM 5.7+, SQM-L 20.9
NELM 5.4+, SQM-L 20.6: Easily split, but rather unspectacular. Just for completeness ;-)

8" f/6, 37x, Bortle 4, NELM 5.7+, SQM-L 20.9
NELM 5.4+, SQM-L 20.6: Evident double star with almost equally bright components and no noticeable contrast in color.
