NGC 6231: Northern Jewel Box

NGC 6231
, also known as the Northern Jewel Box, is an open cluster located near Zeta Scorpii. This cluster is estimated about 3.2 million years old, and is approaching the Solar System at 22 km/s. The cluster belongs to the young Scorpius OB1 association. Zeta1 Scorpii (spectral type O8 and magnitude 4.71.) is the brightest star in the association, and one of the most radiant stars known in the galaxy.

NGC 6334 (also known as the Cat’s Paw NebulaBear Claw Nebula) is an emission nebula located in the constellation Scorpius. It was discovered by astronomer John Herschel in 1837, who observed it from the Cape of Good Hope in South Africa.
NGC 6357, is a diffuse nebula near NGC 6334 in the constellation Scorpius. The nebula contains many proto-stars shielded by dark disks of gas, and young stars wrapped in expanding “cocoons”.

The Butterfly Cluster in Scorpius

The Butterfly Cluster (cataloged as Messier 6 or M6, and as NGC 6405) is an open cluster of stars in the constellation of Scorpius. Its name derives from the vague resemblance of its shape to a butterfly.

The first astronomer to record the Butterfly Cluster’s existence was Giovanni Battista Hodierna in 1654. However, Robert Burnham, Jr has proposed that the 1st century astronomer Ptolemy may have seen it with the naked eye while observing its neighbor the Ptolemy Cluster(M7). Charles Messier catalogued the cluster as M6 in 1764. It was not till the 20th century that star counts, distance, and other properties were measured.

Nebula SH2-9 in the Scorpius

This nebula  lies next to the famous globular star cluster known as Messier 4. SH2-9 has an excellent reflection nebula around the star itself which is surrounded by the nice red emission part of this nebula. The nebula responds very well to a Hydrogen Alpha filter, but you will need a long exposure to capture the nebula that extends around the main star. You need to be careful of getting strong reflection from Antares which is not far, so you may want to include Antares into the image if you can. The H-Alpha channel will hide the reflection nebula seen in this image, so you will need to be careful when processing it.

M7: Open Star Cluster in Scorpius

Image Credit & Copyright: Lorand Fenyes

M7 is one of the most prominent open clusters of stars on the sky. The cluster, dominated by bright blue stars, can be seen with the naked eye in a dark sky in the tail of the constellation of the Scorpion (Scorpius). M7 contains about 100 stars in total, is about 200 million years old, spans 25 light-years across, and lies about 1000 light-years away. The above deep image, taken last June from Hungary through a small telescope, combines over 60 two-minute exposures. The M7 star cluster has been known since ancient times, being noted by Ptolemy in the year 130 AD. Also visible are a dark dust cloud and literally millions of unrelated stars towards the Galactic center.
