Caroline Herschel's Deep Sky Objects

Besides and before assisting her brother, William Herschel, in his great Deep Sky survey starting in late 1782, Caroline Herschel herself was an avid astronomical observer, and discoverer of comets (she originally found 8 of them) and deepsky objects. William Herschel has included her discoveries in his catalog, and assigned numbers to them.

M     NGC       Herschel   RA       Dec     Con  Type

M110  NGC  205  H V.18     00:40.4  +41:41  And  G E5p

      NGC  381  H VIII.64  01:08.3  +61:35  Cas  OC
      NGC  659  H VIII.65  01:44.2  +60:42  Cas  OC
      NGC  891  H V.19     02:22.6  +42:21  And  G Sb  (according to W.H. Smyth)
      NGC 2204  H VII.13   06:15.7  -18:39  CMa  OC    (appendix to W.H.愀 1st catalog)
      NGC 2349  H VII.27   07:10.0  -08:37  Mon  non-existent
      NGC 2360  H VII.12   07:17.8  -15:37  CMa  OC
M 48  NGC 2548  H VI.22    08:13.8  -05:48  Hya  OC
      NGC 6633  H VIII.72  18:27.7  +06:43  Oph  OC      
      NGC 7380  H VIII.77  22:47.0  +58:06  Cep  C+N
      NGC 7789  H VI.30    23:57.0  +56:44  Cas  OC

Unless otherwise noted, the Caroline Herschel findings were looked up in John Herschel's General Catalogue.

In a posting to the Netastro Catalog email list (netastrocatalog-announce@latrade.com), William C. Bryson points out that from above list, NGC 891 and NGC 2204 might be mis-assignments (this email is also source of the NGC 2204 entry in this page; thanks !)

Please email me any additions, corrections, or comments. Especially, one source gave the number of 14, but didn't identify them, so, if you can, please help me with the remaining one.
