Tarazed | – | Alshain | 4 |

Deep Sky Objects…
E Nebula || Banrard’s Nebula || Pair of dark Nebula || NGC 6751 || Dandelion Puffball or Glowing Eye Nebula || Planetary Nebula NGC 6709 || Open ClusterAll 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 44 such different types of Deep Sky Objects observed. Below is the list of 20 brightest Deep Sky Objects are listed below.
