    This is a great galaxy group! (WBL 685). I viewed all but one of the members (MCG +06-49-057) with my 18-inch back in 2004, but Jimi Lowrey and I had a better look in my 24-inch from Grandview Campground in August 2007. At the north edge are two NGC galaxies, 7342 and 7345. The second one is a very nice edge-on, so I've also included my notes on it.

    MCG +06-49-056 = CGCG 514-078 = WBL 685-002 = PGC 69378
    22 38 25.1 +35 21 57
    V = 14.3; Size 1.0'x0.3'; PA = 24°
    Fairly faint, elongated 5:2 SSW-NNE, 0.5'x0.2', bright core. Located 2.3' NNW of UGC 12127 and 1.0' SW of a mag 11.4 star. MCG +06-49-057 is attached at the NNE end.

    MCG +06-49-057 = PGC 67379
    22 38 26.3 +35 22 22
    V = 15.2; Size 0.3'x0.3'
    Extremely faint and small, round, 5" diameter. This quasi-stellar "knot" is attached to the NNE end of MCG +06-49-056 and was visible about half the time. A mag 11.4 star is 32" NNE and interferes with viewing.

    UGC 12127 = MCG +06-49-058 = CGCG 514-080 = WBL 685-003 = PGC 69385
    22 38 29.5 +35 19 41
    V = 13.4; Size 1.5'x1.5'; Surf Br = 14.3
    Moderately/fairly bright, irregularly round, 40" diameter, contains a bright core that increases to the center. Brightest in an excellent group of galaxies (WBL 685) including MCG +09-49-060 1.3' NE, MCG +09-49-062 1.7' E, MCG +09-49-056 2.3' NNW, MCG +06-49-061 3.0' N.

    MCG +06-49-061 = CGCG 514-081 = WBL 685-004 = PGC 69386
    22 38 30.2 +35 22 41
    V = 14.5; Size 0.9'x0.3'; Surf Br = 13.3; PA = 147°
    Very faint, fairly small, very elongated 3:1 NNW-SSE, 0.6'x0.2', brighter core, very faint extensions. Situated close following [33"] a mag 11.3 star in the UGC 12127 group. UGC 12127 lies 3.0' S, MCG +06-49-056/057 is 1.3' SW, LEDA 3966329 is 1.2' NE and LEDA 3088581 is 3.1' NNE!

    LEDA 3966329 = 2MASX J22383404+3523340
    22 38 34.0 +35 23 34
    V = 15.8; Size 0.3'x0.3'
    Extremely faint and small, round, 8". Situated just 20" NW of an 8" pair of mag 13.5-14 stars and 1.2' NE of MCG +06-49-061 in the UGC 12127 group. This galaxy is the faintest of 8 that I logged in the central part of the cluster.

    MCG +06-49-060 = PGC 69384
    22 38 34.8 +35 20 29
    V = 14.3; Size 0.4'x0.4'
    Faint, small, round, 15" diameter. Forms a small triangle with a mag 15 star 21" N of center and a mag 15.4 star 25" SE. Located 1.3' NE of UGC 12127 with MCG +06-49-062 1.1' SSE.

    LEDA 3088581 = 2MASX J22383477+3525390
    22 38 34.8 +35 25 39
    V = 14.7; Size 0.6'x0.3'; PA = 95°
    Fairly faint, fairly small, elongated 2:1 E-W, 20"x10", weak concentration. A mag 12.5 star (unequal double) is 0.9' SSW. Located 6' NNE of UGC 12127 and 3' NNE of MCG +06-49-061.

    MCG +06-49-062 = PGC 69389
    22 38 37.7 +35 19 32
    V = 15.1; Size 0.3'x0.3'
    Faint, very small, round, 15" diameter. Situated 1.7' E of UGC 12127 in the core of the cluster with MCG +06-49-060 1.1' NW.

    NGC 7345 = UGC 12130 = MCG +06-49-064 = CGCG 514-083 = WBL 685-005 = PGC 69401
    22 38 44.8 +35 32 26
    V = 14.3; Size 1.2'x0.2'; Surf Br = 12.6; PA = 39°
    Moderately bright and large, edge-on 6:1 SW-NE, 1.0'x0.15', relatively large bright core, the extensions taper at the tips. A mag 9.6 star is 1.8' S. Furthest north in the UGC 12127 Group (WBL 685) with NGC 7342 7' SW and CGCG 514-087 6.8' SSE.

    MCG +06-49-066 = CGCG 514-087 = WBL 685-006 = PGC 69406
    22 38 58.7 +35 26 19
    V = 14.2; Size 0.5'x0.4'; Surf Br = 12.4
    Fairly faint, small, round, 18" diameter, gradually increases to a small brighter nucleus. Located 5.4' SE of a mag 9.6 star and 6' NW of a mag 8.9 star.
