Deep Sky Objects…
Butterlfly Nebula or NGC 2346 || Planetary Nebula
Cone Nebula || Difffuse Nebula
Dreye’s Nebula or IC 447 || 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 61 such different types of Deep Sky Objects observed. Below is the list of 20 brightest Deep Sky Objects:
Hubble’s Variable Nebula or NGC 2261 || Variable Reflection Nebula
M50 or NGC 2323 || Open Cluster
NGC 2170 || Reflection Nebula
