Historical observations

William Herschel (c.1784)

Synonyms: H I-281

Discovered in 1798 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "cB, E np-sf, nucleus in the middle, 6' long, 1.5' broad."

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 "very bright; very large; very much elongated; pos 118.3 ; 1st gradually then suddenly much brighter to the middle to a nucleus 4' long 1.5' broad has a star 9th mag N.f." He later described it as "pretty bright; very much elongated; pretty suddenly little brighter in the middle; 2.5' long." His final observation recorded it as being "very bright; large; very much elongated; pretty suddenly pretty much brighter to the middle; has a 10th mag star N.f."

Modern observations

Clarke, W.P. (1992)

William P. Clarke (San Diego, California, USA) writes in the The Webb Society Nebulae and Clusters Section Report No. 10, July 1992: "Elliptical haze with a bright, elongated nucleus. PA about 120 degrees. (21-inch f/20, x140)."

Sweetman, Michael E. (1992)

Michael E. Sweetman (Tucson, Arizona, USA), observing with a 12x40 binoculars, writes in the The Webb Society Nebulae and Clusters Section Report No. 10, July 1992: "Not easily spotted at x48, just north of a bright field star. The galaxy is elongated in an east-west direction and the edges are fuzzy and faint. It has a star-like nucleus and a bright bar runs through the nucleus and into the outer extensions. Envelope is faint."

Tom Lorenzin

Tom Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "11M; 3'x 2' extent; ellipse-shaped spiral; fairly bright; 35' NW of 5.5M Tau SCL."

Ancient City Astron.Club (1980)

Listed by the Herschel Club, described as "slight elongation visible in bright nucleus. Situated near bright field stars. 8-inch, 48x."

AJ Crayon

AJ Crayon, using an 8" f/6 Newtonian, notes: "is a spiral galaxy. It is 6'X3' 10m, in position angle southwest, has a brighter middle of 2'x2, a much brighter middle of 1'x1', at 100x. Averted vision helps with this galaxy, use it."

Steve Coe

Steve Coe, in "SACNEWS On-line for November 1996" notes: NGC 613 looked pretty bright, pretty large, bright middle and elongated 3 X 1. There is a pretty bright star on the NE side at 100X. The outer tips of the spiral arms curve in opposite directions as if to show the direction of spiral motion. See if you agree at 1 hr 34.3 and -29 25.

My first observation of this galaxy was made in November 1995 from a site in southern Wisconsin. Ten years later, I revisited NGC 613 with the 18-inch Obsession from a truly dark site in northern Arizona. Observing at 199X, the bright central bar is the most obvious feature, running 5'.5 in length and punctuated by a stellar core region. The initial curl of the northern spiral arm is readily apparent. But the remainder of this arm and the southern arm are averted vision details. Both are challenging detections in the thick air 25� above the horizon. But they give the galaxy an overall width of 4'. The several knots in the southern arm appear to correspond to HII regions in long exposure photos and CCD images of this galaxy. The bright star 2'.4 northeast of the core is unidentified in MegaStar. The double star 7'.5 northwest of NGC 613 is identified as a single 9.8 magnitude object in the Henry Draper and other catalogs. Of the ten remaining stars peppering the field, the brightest is a mid-12th magnitude spark and the others range from 13th to 15th magnitude.

Contemporary observations

Auke Slotegraaf

1997 November 29

1997 November 29/30, Sat/Sun: Jonkershoek, seeing 3, transparency 3, sky darkness 4, lim.mag. at south pole 6.0 (naked eye), 10.7 (binoculars at pole) Strong SE wind. 11x80 binoculars. "A busy starfield; one of the fainter members, a 9.5 mag star, with averted vision, has a fuzzy extension to the south. Close by to the north-west is a similar magnitude star with no such nebulous appendage."

Magda Streicher

1997 November 20

Location: Pietersburg. ( South 23 53. East 29 28).

Sky conditions: Very good 7 magnitude.

Instrument: Meade 12 inch (Eyepiece super 40mm).

Date: 20 November 1997.

Field of view: 52.7 arc minutes.

Neat dainty little roundish elongated haze of light. Sort of a bar shape, low surface brightness and a star close by to the east. Very faint object in a busy starfield.

(no date)

12-inch f/10 SCT (EP: 2-inch 40mm SW 76x 53' fov; 2-inch 14mm UW 218x 23' fov; 2-inch 8.8mm UW 346x 15' fov)

Neat, dainty small and fat haze of light. The middle bright part more or less 2' arc minutes in diameter displayed a slightly bar shape which could be optical illusion on a low surface brightness (218x and 346x). A yellow 9.7 magnitude star can be seen 7.5' arc minutes to the northwest. Very faint galaxy in a relatively busy star field.

[1h 34m 18s, -29� 25' 0"] An elogated (1:5) edge on, with a bright nucleus and a uniformly bright halo. B: SBc. WikiSky: A bright bar and faint arms give the edge on appearance.

Sky Conditions:The fainter parts of the Milky Way are barely visible.Haziness only visible on the horizon.Atmosphere stable with little interference.

Instrument:12-inch Dobsonian.

This galaxy has an almost oval-like shape that looks like an out of focus baked bean.This galaxy has an uneven core and nonstellar nucleus.In overall the galactic nucleus of this galaxy is very condensed which looks like a uniform smudge of faint light.This galaxy measures 3.2'x 2.2'with P.A./NW-SE.Chart No:371,NSOG,Vol.1.
