September Skies offer good potential for deep sky observing, especially here in the dry season the clouds in the NT in northern Australia. Wait until the skies are clear and moonless you can seek out the same delights in the night sky
globular clusters -.
Prominent early evening in the southern sky (if you’re in the northern hemisphere), and at or near the zenith if you are in a great southern hemisphere, the constellation Sagittarius (The Archer), better know as “kettle” . Once you have selected it out in the night sky you will see the familiar teapot shape easily and certainly much easier than you will see Archer! This constellation and adjacent constellation of Ophiuchus (serpent bearer) and Scorpius (The Scorpion) are rich in deep sky delights, especially globular clusters. The most prominent of them being Messier cataloged M4, M28, M22 and M55 just to name a few of the brighter ones
What A Messier Catalogue -.?
Well it goes like this: Well-known Comet hunter Charles Messier 18th century France, the need to store things that could be confused with comets in small telescopes of the day. So he the brightest 100 or so objects in the night sky (from Paris) that became M1 to M110, the last to be added of his colleagues on the go. So the upshot for us in the 21st century is that we now have a simple list of galaxies, nebulas, star clusters and more, which are quite lovely in terms of thought Amateur telescopes with optics that good old Charles could only dream of in 1700. For those of us in southern hemisphere trade has very obvious gaps, with many delights of deep space seen here to be bigger and brighter than 3/4 of shares in Messier list! (They will be the subject of a future article)
Beyond globular clusters –
course delights of deep space to be seen here are not limited to globular clusters, however, with the Lagoon Nebula (M8 ), the Trifid Nebula (M20) Eagle Nebula (M16) and the Sagittarius star cloud (M24) are definitely in the top 20 of all deep sky objects.
So how do you find these & see these amazing deep space delights?
