NGC 5800
Discovered (Jul 8, 1834) by John Herschel
A 7th-magnitude group of stars in Lupus (RA 15 01 47.8, Dec -51 55 06)
A small grouping of a few (four or five?) moderately bright stars. |

NGC 5801 (= PGC 53596)
Discovered (Jun 10, 1885) by Francis Leavenworth (I-215)
A 15th-magnitude spiral galaxy (type Sb?) in Libra (RA 15 00 25.9, Dec -13 54 13)
The second IC lists a corrected position (per Howe) of RA 14 52 44, NPD 103 20.8.
NGC 5801 is the westernmost of a trio of galaxies including NGC 5802 and 5803. Its apparent size is 0.9 by 0.6 arcmins; nothing else seems directly available, but if it is physically associated with NGC 5802, as its distorted shape suggests, it is about 350 million light years away and 90 thousand light years across. |

NGC 5802 (= PGC 53601)
Discovered (Jun 10, 1885) by Francis Leavenworth (I-216)
A 14th-magnitude lenticular galaxy (type S0?) in Libra (RA 15 00 29.9, Dec -13 55 06)
The second IC lists a corrected position (per Howe) of RA 14 52 48, NPD 103 21.7.
NGC 5802 is the southernmost of a trio of galaxies, including NGC 5801 and 5803. Based on a recessional velocity of 7535 km/sec, the galaxy is about 350 million light years away. Given that and its apparent size of 1.3 by 0.9 arcmins, it is about 130 thousand light years across. |

NGC 5803 (= PGC 53609)

A 15th-magnitude lenticular galaxy (type E/S0?) in Libra (RA 15 00 34.4, Dec -13 53 38)
The second IC lists a corrected position (per Howe) of RA 14 53 16, NPD 103 20.2.
NGC 5803 is the easternmost of a trio of galaxies, including NGC 5801 and 5802. NGC 5803's apparent size is 0.9 by 0.4 arcmin; nothing else seems to be directly available, but if it is physically associated with NGC 5802 it is about 350 million light years away, and 90 thousand light years across. |

NGC 5804 (= PGC 53437)
Discovered (May 15, 1787) by William Herschel

Apparent size 1.2 by 1.1 arcmin

NGC 5805 (= PGC 53435)
Discovered (Apr 3, 1854) by R. J. Mitchell
A 15th-magnitude compact galaxy (type C) in Boötes (RA 14 57 11.7, Dec +49 37 43)
Per Dreyer, NGC 5805 (= the 3rd Lord Rosse = GC 4020, 1860 RA 14 52 31, NPD 39 47.5) is "small". As always, the attribution to the 3rd Lord Rosse includes objects discovered by his assistants, as listed above in this case. Corwin states that (Mitchell) sketched the object to the south-southeast of NGC 5804. The position precesses to RA 14 57 07.6, Dec +49 38 41, about an arcmin to the northwest of the object; but that position and the galaxy itself are in the appropriate part of his sketch, so the identification is certain. Corwin adds that several of the objects observed in this area were mislabeled in the 1973 Revised NGC, and the result is a number of errors in the subsequent literature as to which galaxies correspond to which listings. For instance, LEDA also incorrectly lists PGC 53381 as NGC 5805, and a Wikisky search for NGC 5805 shows that same incorrect galaxy. The actual NGC 5805 appears to be a double galaxy, with an apparent size of 0.4 by 0.3 arcmin for the larger, brighter galaxy, and a much fainter smaller companion immediately to its southeast.

NGC 5823 (= OCL 936)
Discovered (May 8, 1826) by James Dunlop (351)

NGC 5824 (= NGC 5834 = GCL 31)

Discovered (1882) by Edward Barnard (and later listed as NGC 5824)
A 9th-magnitude globular cluster (type I) in Lupus (RA 15 03 58.5, Dec -33 04 02)
Dreyer listed this object as being discovered by Barnard, and NGC 5834 as being discovered by John Herschel (many of Dunlop's observations being so poorly reduced that Herschel often received credit for their discovery even when Dunlop's observations were reasonably accurate). The first IC states for NGC 5824, "5824 is = h. 1900 (per Barnard, A.N. 2995). It also occurs in the Cordoba D.M.". Since h.1900 is NGC 5834, the identity of the two entries has been known for more than a century. Normally Dunlop and Herschel's prior discovery would lead to this object being known as NGC 5834; but in the first IC notes for that object (which see), Dreyer recommends striking out NGC 5834, presumably due to the fact that Barnard, who had been given credit for discovering NGC 5824, was also the one who noted its identity with NGC 5834. Apparent size 7.4 arcmin.

NGC 5829 (= PGC 53709, and with IC 4526 = Arp 42)
Discovered (May 11, 1882) by Édouard Stephan (12b-68)
A 13th-magnitude spiral galaxy (type SA(s)c) in Boötes (RA 15 02 42.0, Dec +23 20 00)
Based on a recessional velocity of 5635 km/sec, NGC 5829 is about 260 million light years away, in unusually poor agreement with redshift-independent distance estimates of 145 to 175 million light years. Using an intermediate distance of 200 million light years, the galaxy's apparent size of 1.45 by 1.0 arcmin would correspond to 110 thousand light years. NGC 5829 and IC 4526 make up Arp 42, an example of a spiral galaxy with a faint companion; but the two are not physical companions, as IC 4526 is over 300 million light years further away. |

Discovered (1882) by Edward Barnard (and later listed as NGC 5824)
A 9th-magnitude globular cluster (type I) in Lupus (RA 15 03 58.5, Dec -33 04 02)
Dreyer listed this object as being discovered by Herschel, and NGC 5824 as being discovered by Barnard. The identity of the two objects was noted in the first IC, which states for NGC 5824, "5824 is = h. 1900 (per Barnard, A.N. 2995). It also occurs in the Cordoba D.M.". Since h.1900 is NGC 5834, the identity of the two entries has been known for more than a century. Normally Dunlop and Herschel's prior discovery would lead to this object being known as NGC 5834; but in the first IC notes for NGC 5834 Dreyer says "5834 to be struck out, is = 5824", presumably due to the fact that Barnard, who had been given credit for discovering NGC 5824, was also the one who noted its identity with NGC 5834. So the cluster is generally referred to as NGC 5824, and this entry will only contain historical information (therefore, for physical data and images, see NGC 5824).

Recessional velocity 2200 km/sec, close enough to that of NGC 5846 that they are probably members of the same group of galaxies, though whether they are as close as they appear or physically interacting is not obvious. In fact, the lack of any obvious distortion suggests that the smaller galaxy probably lies in front of or behind the larger one, rather than within its direct sphere of influence (as opposed to NGC 5850, which despite being further away (in the sky) is obviously distorted by the gravitational influence of NGC 5846).
