Description:
Nice group of several galaxies in eastern Cetus that feature various shapes.
The group easily fits into the FOV of the 22mm Nagler at 78x but the group is
probably best observed at 131x. Every member of this group shows different
shape and brightness.That makes it a beautiful target.
--
1035: 12,2magv, 2,2x0,7. Fairly bright edge-on galaxy elongated NW-SE. The
galaxy does brighten very little towards the elongated center. At 342x the NE
side darkens abruptly as if caused by a dark dust lane. Some mottled structure
is faintly visible with averted vision. A faint 14mag star is superimposed on
the galaxys SE end.
--
1042: 11magv, 4,7x3,6. Huge face-on galaxy with very low surface brightness.
At 131x easily visible but featureless disk. At 342x the galaxy appears very
faint but some mottling is visible now around the faint small core.
--
1047: 13,5magv, 1,3x0,6. At 342x faint but still easily visible oval. A
slightly brighter core is surrounded by a 1x0,5 halo.
--
1048A,B: 14,5magv each. Even at 342x those two galaxies are nothing more than
extremely faint and just non-stellar dots S of NGC1042. Stellar at 131x
magnification.
--
1052: 10,5magv, 3x2. Bright and slightly oval galaxy with approx 2,5x2
diameter. The core is non-stellar but small and very bright. It is surrounded
by a bright halo that shows no detail such as spiral arms or mottling.
Brightest member of the group.
--
1069: 13,5magv, 1,4x0,9. Faint oval of approx 0,6x0,4 size. NGC1069 is fairly
easily visible at 131x as well as 342x but apart from a slightly brighter
center no detail is visible.
