Dunlop, J. (1828) A Catalogue of Nebulae and Clusters of Stars in the Southern Hemisphere, Observed at Paramatta in New South Wales. Phil. Trans. Roy. Soc., 118, 113-151. [1828RSPT..118..113D]
James Dunlop discovered this galaxy from Paramatta, New South Wales, and included it as No. 591 in his catalogue of 1827. Using a 9-inch f/12 telescope, he described it as "a very faint small ill-defined nebula."
John Herschel recorded it as "bright, large, much elongated, but with a round nucleus much brighter than the environing faint atmosphere. PD roughly taken. Transit missed, the observation having been lost by relying on the RA given by Mr. Dunlop's Catalog (3h 25m) which is too great. That here set down is assumed at random as probably nearer the truth."

(Sulentic and Tifft 1973) notes that this is a 12.0 mag galaxy. Their coded description reads SB,BM,BBARW/RG, VFDIF PERIPH SSTR.
This galaxy is listed in the "Third Reference Catalogue of Bright Galaxies" as having an outer ring of 5.43 arcminute diameter.

NGC 1316 and NGC 1365 possibly foreground?
Brightest members: NGC 1399 ( B(0) = 11.15), NGC 1380 ( B(0) = 11.30), NGC 1404 ( B(0) = 11.34), NGC 1326 ( B(0) = 11.75), NGC 1350 ( B(0) = 11.80).
("Galaxies and the Universe", Chapter 14 - Nearby Groups of Galaxies) notes that the five brightest members of the Fornax I Group are NGC 1399, NGC 1380, NGC 1404, NGC 1326 & NGC 1350. He notes that NGC 1316 and NGC 1365 are possibly in the foreground.

Tom Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "11.8M; 3'x 1.5' extent; bright, broad slash with much brighter center and stellar core; 7M SAO 194353 is the bright star a few minutes to the SE"

Sharply concentrated with a very bright 20" round core and stellar nucleus. A very faint star is just W of the S extension and two mag 12 stars are 2.7' SE and 3.0' E of center. Located 6' SW of mag 7.2 SAO 194353. Fornax I cluster member.

Steve Coe, observing with a 13" f/5.6, notes: "Bright, pretty large, elongated 2 X 1 in PA 30, much brighter in the middle at 135X."

Lovely galaxy, displays a dust lane stretching in a north to south direction. Slowly brightens to a small bright core. However, it has a low surface brightness. Some flimsy haziness can be seen towards the west (218x). A few stars and a delicate double star can be seen to the east of this galaxy.

[3h 31m 6s, -33° 38' 0"] A bright nucleus surrounded by an elliptical halo, 1:3. Like M 31, only the nucleus is quite bright. Seyfert? Not a Seyfert: Wikipedia.
Sky Conditions:The fainter parts of the Milky Way are barely visible.Haziness only visible on the horizon.Atmosphere stable with little interference.
This galaxy has an fairly long elongated shape with both extensions which is just being seen at 57x and more detail of it at 75x.The nucleus of this galaxy is somewhat condensed as a very faint oval mist of light.Around the outskirts of this galaxy there are plenty of areas of uneven brightness.The central nucleus of this galaxy is brighter compared to the extensions of this galaxy.This galaxy measures 3.3'x 0.6'with P.A:NNE/SSW.Chart No.199,NSOG Vol.1.
