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. 11, January 1993: "Closely spaced group of three galaxies [NGC 7582, 7590 & NGC 7599]. NGC 7582 is extended N.p.-S.f. and does not have a distinct nucleus. The NGC 7590-9 pair are N.f. NGC 7582. They are both extended Sp-Nf with NGC 7590 half the size of NGC 7599. There is a star between the two and another in the north end of NGC 7590. (10-inch Newtonian, x80)."

Hartung, E.J. (1968) Astron.Obj.South.Tel

Hartung notes: "This striking field contains in an area about 16' across three fairly bright spindles differently orientated, all visible with 10.5cm. In order of RA: 4'x1' pa 150 deg; 2' x 0.7' pa 45 deg; 4' x 2' pa 50 deg. The second is the brightest, and the third the faintest and most diffuse."

Tom Lorenzin

Tom Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "12.0M; 4'x 2' extent; axis oriented NNW-SSE; no obs. data yet; look for SP GAL N7590 (12.5M; 2'x 1' extent) 10' to NE with fairly bright star on NE tip; look for ENE-WSW-oriented SP GAL N7599 (12M; 3'x 1' extent) 4' further E and a bit S with small stars involved; all should make fine trio in medium-x field; see photo Shapgal-202."

Steve Coe

Steve Coe, observing with a 13" f/5.6, notes: "Pretty faint, large, elongated 2.5 X 1 in PA 45 and not much brighter in the middle at 100X. Forms a nice triple galaxy with NGCs 7590 and 7599."

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.

The shape of this galaxy is vaguely long with an extension on both sides and that this galaxy's shape is somewhat elongated.The nuclues of this galaxy is comparitively tight and well defined and that there are some areas of uneven brightness being seen on the far outskirts of this galaxy.There are a few darker areas within the outskirts of this galaxy.The nucleus is brighter compared to the far outskirts of this galaxy.This galaxy measures 5'x 0.8'with PA NNW-to-SSE.Challenge Rating:Difficult.Chart:No.143,NSOG Vol.3.
