Martin Schoenball, 10",91x, fst 6m2:
Large galaxy with pretty low surface brightness. It does not get brighter towards the middle but features a very bright core. The galaxy has some low contrast brighter regeion. A bar runs inclined through the center. The galaxy is elongated 4:1 and has tapered ends.


Matthias Juchert, 2,5", fst 6m4:
Large, oval nebula elongated at PA 30. The pretty low surface brightness und the moderately bright core lead to the assumption of a spiral galaxy even with small telescopes.

NGC 770: Only 3' south of the core of NGC 772 lies this small, and pretty high surface brightness galaxy. It is only visible with averted vision, but appears pretty easy as a small oval nebula at 126x.
NGC 772: NGC 772 is visible with direct vision, but not as bright as the 10m3 indicate, nevertheless the faint, ellipse shows up at 50x. A very much brighter core with a stellar nucleus lies off center in the halo. The halo itself is unusual. At 98x and averted vision a faint extension is visible at the north-west side. There is dark space between the extension and the galaxy body - one spiral arm is visible with 8"!

NGC 5395: Bright galaxy, elongated 2:1 N-S. Later, faint spiral arms winding counter-clockwise are visible. A faint knot lies detached from the northern arm. The southern arm is broader and brighter and extends straight from the main body. The main body is a little brighter towards the middle.
NGC 5394: Faint, very small galaxy, pretty compact with high surface brightness, little elongated NE-SW, little brighter towards the middle, no core.



Uwe Glahn, 16", 257x, fst 6m5+:

NGC 5395: Main part of NGC 5395 is elongated 2:1 N-S; bright core; a prominent arc starts east of the core running south, it extends to the southern tip of the galaxy and makes a slight bend to NW; at the southern end brighter and broader; a detached spiral arm starts at the southern end, beeing brightest near the center and beeing directed towards NGC 5394; at the northern end lies a 3:1 SE-NW elongated knot
NGC 5394: elongated 2:3 NE-SW with homogeneous brightness distribution; a faint thin arced extention starts at the SW end running towards NGC 5395; no extension on the opposite side; 4' NE liea the round 15vmag faint IC 4356; did not look for two further 16,5bmag faint galaxies in the field.

companion already visible in the binos, with 16" bright spiral arms with lots of structure, many brighter spots inside the galaxy body, bridge between M 51 and the companion NGC 5195 hard to detect


Martin Schoenball, 10",91-274x, fst 6m6:
M 51: Very large and bright. The spiral arms are hinted by several knots, but are not circumferential. A 13mag star lies at the inner side of a thin bright arm with a knot in the north. The center is round with extensions E-W. Further east lies a knot. It is difficult to get all details without having a known image in the mind!
NGC 5195: The central area is round and of higher surface brightness than M 51. The brightest part has the shape of a cone pointing towards M 51 and a round center in the middle. Towards E a quarder circle is attached. The slightly oval halo is rotated by 90 degrees against the cone. No visible connection to M 51.


Matthias Juchert, 2,5", fst 6m5:
Very bright, pretty large. Two overlapping disks in a common halo are visible at 34x with M 51 twice as large as NGC 5195. The Halo is elongated 3:1 N-S. Both objects show a very bright non stellar core.

Matthias Juchert, 8", fst 6m8:
Showpiece of a spiral galaxy. Very bright, very large, beautiful! At 98x two prominent clockwise spiral arms with dark bands between them are visible. The brightest parts of the arms are in SW and NW. A 13mag star lies at the inner side of a spiral arm in the southeastern part. Here two knots of light are detectable with averted vision. The one in N is fainter and nearly stellar, there southern one is clearly extended. The companion NGC 5195 shows a bright central area lying sideways in the halo forming the shape of a cat's eye. The halo is more evident and more extended in W. The connection between the two galaxies is difficult to detect.

Interesting pair with NGC 5954. Both appear as one smudge at 50x.
NGC 5953: At 126x the special form of the system can be assumed. Both nebulae are equally bright and overlap. They are not arranged in east-west orientation. NGC 5953 is the larger of the two and has a roundish shape with a bright center.
NGC 5954 is the smaller component of the system a little fainter than NGC 5953. In contrast to photos this galaxy appears oval visually and not oblong.
