bright bar elongated NW-SE, bright core, at the NW and SE end of the bar two brighter spots, longer arm starts SW of the core with two brighter spots, brightest spot at 2/3 in direction N, second brightest spot at the beginning of the arm



Martin Schoenball, 10",139x, fst 6m3:
Bright galaxy, bright core, it is brightest northwest of the center. In all it has a oval shape at low magnification. At higher magnifi. the part in the norhwest is dominating. The center extends faintly towards southeast und leads to a faint but large knot. Elongation about 3:1 SE-NW.


Matthias Juchert, 12,5", fst 7m0:
Long, very bright central area with 2 obvious spiral arms not winding around the core but extending nearly parallel due north and south. Visually not as asymmetric as on photos.

Uwe Glahn, 16", 315x, fst 6m5:
bright, 1:2 NE-SW elongated nucleus within the 3:1 NE-SW elongated galaxy; 2 arms along the galaxy; brightest arm startet at the SE side of the galaxy and runs till till the NE end; second brightest arm is divided by an dark band, starting from SW at the NW side of the galaxy; a third brighter part started seperated from the NE end of the galaxy and is elongated 1:3 NE-SW


Matthias Juchert, 2,5", fst 6m5:
Obvious nebula, medium to small size.

Matthias Juchert, 8", fst 5m8:
The galaxy is easy to find north of the prominent "Y". It is obvious, pretty bright, not quite edge on. The overall shape is long-oval and pretty homogenuous.

Martin Schoenball, 10", 197x, fst 6m4:
bright galaxy, very odd shape: looks like a curled tadpole, broad main part barely brighter to the middle. A broad arm runs counterclockwise away from eastern main part an gets sharper. A knot lies detached to the south. The whole galaxy is surrounded by a pretty faint, circular halo.



Uwe Glahn, 16", 225x, fst 6m7:
dominating 1:3 NE-SW elongated nucleus with mottled structure; its NE-end has some structure to the N; a 2,5' long arm starts on the N-end of the nucleus; the arm is brighter and thicker to its S-end; brightest HII Region IC 3668 is easy to see; a very faint and stellar region is found 45" E of the nucleus


Matthias Juchert, 10" fst 6m4:
A bright and large galaxy with very special details. In a round-oval halo lies an eccentric, bright core. A spiral arm extends from here in direction of a bright star. The arm has different brightnesses. Brilliant!

Uwe Glahn, 4"", 88x, fst 6m5+:
Small, also at 88x, 2:3 N-S elongated; the core is inclines NE-SW and shifted north; fainter in the south.

no spiral arms in the bino


Uwe Glahn, 16", fst 6m3:
galaxy divided into two dominating spiral arms, fainter spiral structure is also visible, many knots in the spirals, bright SSC 6946-1447 is visible with averted vision


Martin Schoenball, 10", fst 6m3:
Bright galaxy, very large, but low surface brightness. No brightening to the center but shows a broad little brighter core. The galaxy is spiraling with one arm on both sides of the large galaxy body attached, swirling counter-clockwise. There is a brighter area the beginning of the eastern arm, as well as at the inner side of this arm. North of the center is a very faint knot. All in all very low contrasts and many stars embedded.


Matthias Juchert, 2", fst 6m5:
The spiral galaxy is visible even in 7x50 binoculars as a very faint nebula. It is much fainter than the neighboring star cluster NGC 6939.

Matthias Juchert, 12,5", fst 6m5:
Very nice view at low power with NGC 6939. Even at 47,5x some details are visible. The center is not very pronounced. The western spiral arm is visible best with a counter-clockwise winding. One can note the width of the arm but can not split it. The northern arm is only very faint and oddly seems to wind clockwise after a straight part.
