Hershel 400 Objects in Cetus
| Abbreviations in the CON column are the IAU versions. |
| The column TYPE has following abbreviations: |
| OPNCL = open cluster |
PLNNB = planetary nebula |
GLOCL = globular cluster |
CL+NB = open cluster and nebulosity |
BRTNB = bright emission or reflection nebula |
| Hubble Classification for galaxies or GALXY where no
classification existed. |
| In the Herschel Column
the Classes are: |
| I = Bright Nebulae |
III = Very Faint Nebulae |
V = Very Large
Nebulae |
VII = Pretty Much Compressed
Clusters of Large or Small Stars |
| II = Faint Nebulae |
IV = Planetary Nebulae |

H II 3 |
Pretty bright, large, elongated 2 X 1 and somewhat
brighter in the middle at 100X. An 11th mag star in involved on the
east side. At 135X this galaxy shows some mottling in moments of good
seeing. |

H V 25 |
is a very nice planetary to break up all these
galaxies. It is bright, large and round at 100X. There are several
dark areas in this nebula and they combine to look like this is a
doughnut someone took a bite from. The UHC filter makes this effect
more noticeable. There are three stars involved at 165X. |

H V 20 |
Pretty faint, very large, much elongated (4
X 1) and has a star at one end. It is not much brighter in the middle
at 100X in the 13". This object was much more conspicuous in
my old 17.5" at 130X. In either scope, this galaxy has a pretty
low surface brightness and does not deserve the 10th mag rating it
gets in many listings. The outer portions are mottled in both scopes,
with good seeing. |

H I 63 |
Pretty bright, pretty small, round, much brighter
middle. This is the brightest galaxy in a small group. The central
three galaxies offer an interresting contrast. NGC 1052 is round and
pretty noticeable at 100X. One nearby companion is round and very
faint, while another is pretty faint and elongated 3 X 1. They all
fit in a 20 mm Erfle eyepiece which has a 30' field and gives 100X
on the 13". A very nice grouping. |

H I 1 = H II 6 |
Pretty bright, pretty large, much elongated
(3 X 1), bright middle. Averted vision makes this object grow larger
and will just bring out a dark lane running along the galaxy edge. |
