DSS
© DSS II (red) - 100×100'
Name: Collinder 399, Coathanger
Type: AST
Constellation: Vul
Coordinates: 19h26m20.00s / +20°07'40.00"
Brightness / Size: v3.6 mag / 100.0x40.0'
Prominent cluster of brighter stars. On the eastern end the fairly faint open cluster NGC6802 can be found.

B 40mm, 8x, Bortle 5, NELM 5.5
Wonderful object for binoculars. Evident shape of a coathanger.

EASY
8" f/6, 37x, Bortle 4
Evident. Some brighter stars forms the typical shape of a coathanger.

NGC6800 (OC)

DSS
© DSS II (blue) - 10×10'
Name: NGC6800, H8.21
Type: OC
Constellation: Vul
Coordinates: 19h27m06.00s / +25°08'00.00"
Brightness / Size: - / 5.0x5.0'
80mm f/6.25, 25x
Observation under partly clouded urban sky. The cluster appeared at 25x more like a star cloud. At 83x some stars were seen. Moderate contrast to the surrounding.
EASY

NGC6802 (OC)

DSS
© DSS II (blue) - 8×8'
Name: NGC6802, H6.14
Type: OC
Constellation: Vul

Brightness / Size: v8.8 mag / 3.2x3.2'
8" f/6, 133x, Bortle 5
At 37x just a slightly elongated brightening with averted vision. At higher magnification many faint stars were seen.
EASY

NGC6815 (AST)

DSS
© DSS II (blue) - 10×10'
Name: NGC6815
Type: AST
Constellation: Vul
Coordinates: 19h40m44.00s / +26°45'32.00"
Brightness / Size: - / 3.0x3.0'
8" f/6, 37x, Bortle 4
A group of moderately bright stars. Somewhat evident.
EASY

NGC6830 (OC)

DSS
© DSS II (blue) - 12×12'
Name: NGC6830, H7.9
Type: OC
Constellation: Vul
Coordinates: 19h50m59.00s / +23°06'00.00"
Brightness / Size: v7.9 mag / 12.0x12.0'
B 40mm, 8x, Bortle 6-, NELM 5.3, SQM-L 19.3
Fairly faint, small, less conspicuous.

MODERATE
4.5" f/8, 75x, Bortle 7, NELM 5.0
About 5 stars visible with direct vision, about 10 stars with averted vision. Mainly fainter stars fairly scattered without considerable concentration toward the middle. Relatively good contrast to the surrounding. Shape more elongated.
MODERATE

NGC6882 (AST)

DSS
© DSS II (blue) - 18×18'
Name: NGC6882, H8.22
Type: AST
Constellation: Vul
Coordinates: 20h11m54.00s / +26°49'00.00"
Brightness / Size: v8.1 mag / 18.0x18.0'
80mm f/6.25, 25x, Bortle 6, NELM 5.0
NGC6882 is extended over a larger field and contains some brighter and fainter stars, which are scattered more or less apparent between 19 Vul and 20 Vul.
EASY

NGC6885 (OC)

DSS
© DSS II (blue) - 15×15'
Name: NGC6885, H8.20
Type: OC
Constellation: Vul
Coordinates: 20h12m01.00s / +26°28'42.00"
Brightness / Size: v8.1 mag / 7.0x7.0'
8" f/6, 200x, Bortle 4
Indeed I could see a couple of faint stars, but an assignment to the cluster is actually hard. I also observed this cluster with smaller aperture and lower magnification.

NGC6940 (OC)

DSS
© DSS II (blue) - 50×50'
Name: NGC6940, H7.8
Type: OC
Constellation: Vul
Coordinates: 20h34m26.00s / +28°17'00.00"
Brightness / Size: v6.3 mag / 31.0x31.0'
B 40mm, 8x, Bortle 4-, NELM 5.7+, SQM-L 20.9
Evident, relatively large, evenly bright, diffuse, oval. At the northeastern and southern edge 2 moderately bright stars.

EASY
80mm f/6.25, 25x, Bortle 6-, NELM 5.0
At 25x about 7 stars but nothing else apparent. At 83x some more, fainter stars. Not noticeable as a cluster.

DIFFICULT
8" f/6, 37x, Bortle 4
Large, rich cluster with many fainter and moderately bright members. Star density varies within the cluster and is much higher than the surroundings. No concentration toward the middle apparent.
