Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /home/yivumoo/public_html/show_object.php on line 167

History and Accurate Positions for the NGC/IC Objects (Corwin 2004)

NGC 7418. Dreyer suggested that this might be IC 5265 (which see), but it is not.

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, vL, R, or vlE, vgbM, 4' diam, with left eye resolvable, hardly resolved, PD bad. A fine object." On a second occassion he called it "B, vL, R or vlE, vglbM, 5'." His third observation was recorded as "vF, vL, R, vglbM, 3'."

Swift, Lewis (1896)

See Swift's comments on IC 5264.

Published comments

Helwan Obs. Bulletin No 9 (1912)

F, 2' ino diameter, spiral.

Helwan Obs. Bulletin No 22 (1921)

F, 2.5'x2.5', spiral with pF alm.stell.N. This is a 'left-hand' spiral with two main branches which are close together on the f. side, and from these proceed a number of smaller subsidiary whisps.

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).

Shobbrook (1966)

Shobbrook (1966, Mon. Not. R. astr. Soc., Vol 131, p351-363) notes that this member of the Grus Cluster has V = 11.77, B-V = 0.60 and U-B = -0.05. It measures 3.2 by 2.2.

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a 12.0 mag galaxy. Their coded description reads S,VDIF,LBM,DKLNS, SEV KNS IN CT.


A supernova erupted in this galaxy in 1983 (15.5p)

Sandage (1975)

Sandage (1975(Astrophysical Journal, 202, 563-582) notes that this galaxy is a member of the IC 1459 Grus Group. Members include NGC 7410, NGC 7412, NGC 7418, NGC 7421, NGC 7424, NGC 7496, NGC 7531, NGC 7552, NGC 7582, NGC 7590, NGC 7599, IC 1459, IC 5267, IC 5269 & IC 5273.

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

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

Lovely large round glow situated between four block stars which is away more or less 5' to the sides, it resembles the Crux constellation. Very soft to the edges but slightly oval in a NW-SE direction.
