Corona Australis (Dakshin Kirkit)
Corona Australis, resembles the shape of a crown, when stars in this constellation are imaginarily connected, as per Indian mythology!
Where should I see…Scorpius and Ara, is the constellation which is towards west of Corona Australis
constellation. If you move your eyes towards east, you will see another constellation named Sagittarius. In the North and South of Corona Australis, you will find Sagittarius and Telescopium constellations respectively. Corona Australis is halfway between celestial equator and South Pole, and so is fully part of Southern Hemisphere.
It covers up 182 square degree area of the sky. Area wise it is 80th largest constellation in the sky.
We can gaze at this crown shape of Corona Australis constellation from November to July, as seen from India.
When and What can I see…All you need is your naked eyes other than clear skies to see 44 stars of this
constellations, as they are the one which are brighter than the lower limit of our naked eyes (i.e. 6.5 apparent magnitude) to see faintest stars.. The brightest star of this constellation is Alpha and Beta Coronae Australis.
Constellations are made up of single, binary (apparent and absolute), multiple and variable stars. Out of total 44 stars of different types, here is the list of 20 brightest stars as per their nature:
| Binary / Multiple Star system | Variable Stars | Binary and Variable Stars | Single stars |
| 1 | 3 | 2 | Meridiana |
| 13 | |||
| 1 | 3 | 2 | 14 |
As per Hindi mythology, there are no such known stories for this constellation.
Deep Sky Objects…
Corona Australis Star Cluster
Coronet Cluster || Open Cluster
NGC 6726 || Reflection Nebula
All the stars that we see naked eyes, all belong to our own, Milky way galaxy (Akash Ganga Tara Vishv). Bright stars can be seen naked eye and faint one through telescope. But the curtain of sky that we see in 2D is actually a huge universe we are talking about, with 3 dimension. There are many nebulous objects visible in every constellations. They differ widely by distances and nature. Like Emission Nebula, Reflecting Nebula, Absorption Nebula, Star Birth Nebula, Supernova Remnants (SNR) and Open Stars cluster which are within the disk of our own Milky Way galaxy. Globular cluster are also found, which are in the halo of our galaxy and some most distant objects like galaxies are also visible through telescope. Such objects are defined as “Deep Sky Objects”.
In this constellation there are 9 such different types of Deep Sky Objects observed. Below is the list of 20 brightest Deep Sky Objects:
