NGC5617 (Bennett 65) is a mag. 6.3 open cluster located 1.2° west of Alpha Centauri, just north of an imaginary line drawn between Alpha and Beta. Dreyer's description reads: Large (10'), richer in stars to the west (about 80 total), with a compressed middle. It contains stars of magnitude 8 and fainter. While visible in binoculars as a hazy patch, a 6" begins to resolve the cluster well at higher magnifications.
NGC5460 is a mag. 5.6 open cluster located 2.3° ESE of Zeta Centauri. Described as very large (25'), and very little condensed, it has about 40 stars mag. 8 and fainter. The small (2.8'x1.7') galaxy just to the north is the mag. 12 ESO221-26.
NGC5286 (Bennett 64, Caldwell 84) is a globular cluster located 4.3° SSW of Zeta Centauri. Described as very bright (mag. 7.6), fairly large (9'), round, and extremely rich, it has stars mag. 15 and fainter.
NGCs 5281 and 5316 are two open clusters in a rich field. NGC5316 lies 1.2° north-west of NGC 5281. NGC5316 is located 1.9° south-west of Hadar (Beta Centauri). NGC5316 is described as fairly large (14'), fairly condensed, with about 50 stars mag. 11 and fainter. Overall magnitude is 6. NGC 5281 is bright (mag. 5.9), small (5'), and fairly condensed, containing about 20 stars of mags. 10-12.
NGC5253 (Bennett 63a) is an irregular galaxy located in northern Centaurus near the Hydra border. It forms an equilateral triangle with 6-7° sides with the stars Theta and Iota Centauri. It also lies 1.8° SSE of M83 in Hydra. NGC5253, M83, NGC4945, NGC5128, form a physical association. Dreyer describes NGC5253 as bright, fairly large, and extending in roughly p.a. 45°. It brightens westward abruptly toward a much brighter middle. While this brightening is true for larger telescopes, a 6" will show an evenly illuminated oval.
NGC5128 (Bennett 60, Best 17, Caldwell 77) is also known as the radio source, Centaurus A. Some viewers call this the "Hamburger Galaxy," for the dark meat patty between two pieces of white bread effect, easily visible in a 6". Located 4.5° west of Mu Centauri, and the same distance north of Omega Centauri, Dreyer calls it a very remarkable object. Very bright (mag. 7.2), very large (18'x15'), and very much elongated (P.A. 122), the dark center band divides it neatly in two.
Omega Centauri (NGC5139, Best 18, Bennett 61, and Caldwell 80) resembles a fuzzy star to the naked eye, but resolves into the premier globular cluster of the heavens in any sized telescope. Dreyer confirms this by giving it a triple exclamation point. He calls it bright (mag. 3.7), extremely large (36'), extremely rich, and very, very condensed. The stars are mag. 11 and fainter. Located 4.8° west of Zeta Centauri.
NGC5102 is a spiral galaxy located near (17') Iota Centauri in northern Centaurus. Described as very bright (mag. 10), large (8.8'x2.9'), and elongated, it has a sharply defined nucleus.
NGC4945 (Bennett 57, Caldwell 83) is a nearly edge on spiral galaxy described by Dreyer as bright (mag. 9.2), very large (20'x4'), and very much elongated (P.A. 39). It is located between Xi2 and Xi1 Centauri in the center of this huge constellation.
Many other galaxies inhabit the area of NGC4945. Amateurs should have little difficulty with NGC4976 (Bennett 58), 3.3° east. It shines at mag. 11. NGC4945a to the south of the main galaxy shines at mag. 13. ESO219-27 shines to its south. ESO219-22 and ESO219-22a shine 30' west of NGC4945. These galaxies shine at 14.5 and fainter.
Caldwell 100 (IC2944) is a mag. 4 open cluster with nebulosity almost centered on Lambda Centauri near the Crux border. Dreyer describes it as a mag. 3.4 star (Lambda) embedded in a very large (60'x35') nebulosity. Visually the nebulosity is fairly faint. The associated cluster has about 30 scattered stars at mag. 6.4 and fainter.
Caldwell 97 (NGC3766) is a mag. 5.3 open cluster located in the Milky Way 1.4° north of Lambda Centauri near the Crux border. Dreyer describes it as fairly large (12'), fairly rich, and fairly condensed, containing about 100 stars mag. 8-13.
The Blue Planetary (NGC3918) is one of Dreyer's remarkable objects. It is small (12"), round, blue, and looks like a defocused mag. 7 star (actual brightness is described as 8.4). There is a central star at mag. 13.3. It lies mid-way between Delta Crucis and Pi Centauri near the Eastern Crux border.
NGC3960 (Bennett 48) is an open cluster located 1.5° north of NGC3918. Dreyer describes it as fairly large (7'), becoming richer in stars and brighter. It contains about 45 stars of magnitude 11.5 and fainter. Total magnitude is 8.3.
