7 Sisters of the Pole (AST)

Name: 7 Sisters of the Pole
Type: AST
Constellation: Cep
Coordinates: 23h30m00.00s / +86°00'00.0"
Brightness / Size: - / 240.0×120.0'
Very large asterism with best view in binoculars at low magnification. This asterism looks like the Pleiades (Messier 45) and is dominated by the stars HD217382, HD217157, HD212710, HD221525 and 2 Cephei.

B 40mm, 8x, Bortle 8, NELM 4.3+, SQM-L 18.9
Very large, relatively evident. After a short while the similarity to the Pleiades was visible. Fits quite well in the 7.5° large field of view.

King 10 (OC)

DSS
© DSS II (blue) - 20×20'
Name: King 10
Type: OC
Constellation: Cep
Coordinates: 22h55m01.20s / +59°10'12.0"
Brightness / Size: - / 3.0×3.0'
8" f/6, 37x, Bortle 3-, SQM-L 21.2
At 37x quite evident as small, triangle-shaped, granular brightening. North an evident group of brighter stars, to the southeast 5 stars form a '5' of a dice over an area of about 15x15'. At 80x several faint members become visible, the background stays still diffuse. At 150x the cluster seems to be almost entirely resolved. A worthwile cluster in nice surrounding.

Brightness / Size: v7.8 mag / 10.0×10.0'
Evident, rich open cluster, which is located only 40' northwest of the also quite evident and bright spiral galaxy NGC6946. Both objects together give a nice view!

Fairly well visible, large, round, slightly condensed, diffuse.

MODERATE
8" f/6, 37x, Bortle 4, NELM 6.1, SQM-L 21.1
Rich with mainly fainter members. At 37x many fainter stars visible with averted vision, but background appears still granulous/diffuse. Southeast of the center are some brighter stars arranged in a chain, which quite sharply delimits the cluster at 100x (also well visible on the DSS image).
EASY

DIFFICULT
120mm f/5, 40x, Bortle 4, SQM-L 21.0
At 40x just a small, compact glow near two brighter stars. Almost the same view at 75x.

At 37x three stars apparent as an acute triangle. The northeastern star appeared orange to slightly reddish. At 80x some more fainter stars visible. At 200x the cluster appeared somewhat elongated. Higher magnification recommended due to rather small angular size. Overall a quite evident cluster.

EASY
