Historical observations

John Herschel (1847) Cape Observations

Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "pB, vS, pmE, psbM, 15 arcseconds long, 8 arcseconds broad. The preceding of two."

NGC/IC Dreyer (1888, 1895, 1908)

This spiral galaxy is described in the NGC as "pretty bright, small, pretty much elongated, pretty suddenly brighter in the middle, preceding of two." The following galaxy is NGC 7233.

Published comments

de Vaucouleurs, G. (1956)

De Vaucouleurs (1956) "Survey of bright galaxies south of -35° declination", Mem. Mount Stromlo, No. 13. (photographic study, plates taken with the 30-inch Reynolds reflector, 20-inch diaphragm).

Bergwall et.al. (1978)

Bergwall et.al. (1978(Astron. Astrophys. Suppl. 33, 243-255) gives this galaxy's B-magnitude in the Johnson system as 13.57. Photoelectric UBV measurements give V=12.526 for a 44'' diaphragm and V=13.028 for a 22'' diaphragm.

Sandage, A. (1975)

Sandage (1975(Astrophysical Journal, 202, 563-582) notes that this galaxy is a member of the NGC 7213 Group. Members include NGC 7213, NGC 7232, NGC 7233 & IC 5181.

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a 13.0 mag galaxy.

Contemporary observations

Auke Slotegraaf


A 15.5-inch telescope at 220x shows this pair of galaxies in the same field, with NGC 7232 noticeably brighter than its companion. The galaxy appears very obviously elongated, lying west-east and slightly south. Immediately following the galaxy pair are two bright, slightly reddish stars.

1998 August 22

22 August 1998, Farm site, Meade 8" with a 18mm wide angle & 26mm Plossl, 36' fov, Sky Conditions: Clear 7 to 8 magnitude

NGC 7232 soft, faint elongated thin dust lane, with a sudden brighter middle. Again NGC 7233 more roundish and fainter. Close by two bright stars following,

Alldays (22.50S, 20.12E, 770m).

12-inch f/10 SCT (218x, 346x)

NGC 7232 appears as a soft, faint and elongated thin dust lane, with a bright center. To the east two rather lovely yellow 8 magnitude stars follows on the parallel to the north round off the picture. The very faint member NGC 7232B was not visible. In comparison to NGC 7232, NGC 7233 is slightly round and fainter, just east of NGC 7232. To the east two rather lovely yellow 8 magnitude stars round off the picture. The very faint member NGC 7232B was not visible, also call ESO 289-G09?. Brian Skiff I did however manage to find what Magda calls NGC 7232B = ESO 289-G09, but it was too faint in 15cm aperture to see other than a very-low-surface- brightness smudge (total V only ~13 [rather uncertain] and mean surface brightness only muV = 14.4!).
