- The Scorpion – actually looks like it’s constellation name sake
- M4 – You can easily see Large extended, chains just W. of Antares – a globular cluster in the constellation of Scorpius. It was discovered by Philippe Loys de Chéseaux in 1745 and catalogued by Charles Messier in 1764. It was the first globular cluster in which individual stars were resolved
- NGC 6144 – low core stellar density but a host to x-ray sources, nice little tight globular just above and W Antares…at almost 10th magnitude = good conditions here at 50-N
- Halfway from Antares to Graffias, the northernmost right claw star, is M80. 7th magnitude that hosts many blue straggler stars which are much younger than the cluster itself.
- Ngc 6231/Collinder 316 and Trumpler 24 beautiful in binos form the false comet
- NGC 6231 – open cluster in the southern sky located about half a degree north of Zeta Scorpii, the bottom sar in the stinger before the stinger strikes left (east). NGC 6231 is part of a swath of young, bluish stars in the constellation Scorpius known as the Scorpius OB1 association.
- Moving up and east we get to Shaula and Lesath – cat’s eyes
- Just East is M6 the butterfly cluster – really looks like this shape
- SE is Ptolemy’s cluster M7 – NGC 6453 is a little globular appearing caught up in M7 with a couple dark nebulae – B287 in the Southern part within the cluster while B 283 extends out to the North over the Milky Way
Challenging: We’ll work our way back up to the NW
- SW of M7 is NGC 6455 – often mistakenly alleles as an open cluster John Herschel found it on Jun 7 1837 – is “a cluster, partially resolved (some stars seen), stars extremely small plus nebula”. Noted by Dreyer as Probably merely an enhancement of the Milky Way background.
- NGC 6334 & NGC 6357 the Cat’s Paw & The Lobster Nebulae perhaps appearing as a ghostly rendition of M8 and M20/21
- Challenging for this latitude ..frequently find them in wide field instruments when I panned to far west and south on a scan for M8/M20/21
- Cat’s Paw – an emission nebula with a red colour that originates from an abundance of ionized hydrogen atoms. Stars nearly ten times the mass of our Sun have been born there in only the past few million years.
- NGC 6357 The Lobster Nebula is easily found at the end of a chain of 7th magnitude stars, This Nebula / open cluster complex is forming some of the most massive stars known but according to NASA no one knows. Cataloged as NGC 6357, the Lobster Nebula houses the open star cluster Pismis 24 near its center is a home to bright and massive stars. The overall blue glow near the inner star forming region results from the emission of ionized hydrogen gas. The surrounding nebula, holds a complex of gas, dark dust, stars still forming, and newly born stars. The intricate patterns are caused by complex interactions between interstellar winds, radiation pressures, magnetic fields, and gravity.
- vdB 107 surrounding Antares LBN 1103 is an HII region that extends south several degrees
- IC 4592 (also known as the Blue Horsehead Nebula) is a reflection nebula in the Scorpius constellation that is lit by Nu Scorpii. Discovered by Barnard of Dark Nebulae Fame in 1895. Writing from Yerkes in 1897 he detailed his observations with 6 and 12 inch refractors at Mt. Hamilton.
