Tucana, resembles the shape of a bird Toucan (found in a tropical and subtropical regions), when stars in this constellation are imaginarily connected.
Indus, is the constellation which is towards west of Tucana constellation. If you move your eyes towards east, you will see other constellations named Hydrus and Eridanus. In the North of Tucana, you will find Phoenix and Grus while in South, Octans constellation. Tucana is between celestial equator and South Pole, and so is fully part of Southern Hemisphere.
It covers up 295 square degree area of the sky. Area wise it is 48th largest constellation in the sky.
We cannot gaze at this shape of Tucana constellation from India.
Constellation Tucana
All you need is your naked eyes other than clear skies to see 46 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 Tucanae.

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 Starscluster 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 128 such different types of Deep Sky Objects observed. Below is the list of 20 brightest Deep Sky Objects:
NGC 265 || Open Cluster
NGC 104 || Globular Cluster
