Historical observations

William Herschel (c.1784)

Synonyms: H III-458

Discovered in 1785 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "vF, S, easily resolvable."

John Herschel (1847) Cape Observations

Observed by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "Not vF, S, R, bM, 30 arcseconds."

NGC/IC Dreyer (1888, 1895, 1908)

This 13th magnitude spiral galaxy is recorded in the NGC as "faint, small, round, easily resolvable."

Published comments

Burnham's Celestial Handbook

Burnham calls it "faint, small, round, faint extension on west side."

Arp (1966)

Listed as No. 226 in Arp's "Atlas of Peculiar Galaxies" (Astrophysical Journal Supplement, vol. 14, 1966.) He remarks "loops, filaments at various angles."

Sulentic & Tifft (1973)

(Sulentic and Tifft 1973) notes that this is a 13.0 mag galaxy. Their coded description reads R,BM,HISB.

Modern observations

Steve Coe

Steve Coe, using a 17.5" f/4.5, notes: "Faint, small, round, not easy to pick out in a field of faint stars at 100X."

Contemporary observations

Magda Streicher

1998 August

Location: Campsite (23 16 South - 29 26 East).

Telescope: Meade 8" 18mm eyepiece, 36 arcmin f.o.v.

Date: August 1998.

Sky conditions: Not very good.

Description: About the same size and brightness than NGC 7218 but more elliptical, resembles a star out of focus. Lonely star to the west just outside this galaxy.

(no date)

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

12-inch f/10 SCT (218x)

About the same size and brightness than NGC 7218 but more elliptical, resembles a star out of focus. There is a lone star to the west of the galaxy. Quite round and small in shape with a bright inner core. There is a significant degree of haziness close to and around the outer edge. To the western side a lonely star, faint extensions to the west? The galaxy show of a more round shape this time around, but agree with star out of focus. Very hazy to the edges, the core slowly brighter. Bare field of view 12Magnitude star on the western edge. The core is not star like but just brighten with ease.
