There are many astronomical object types that come under the description of deep-sky objects. Since the definition is objects that are not Solar System objects or individual stars, examples include: [10] Black holes [11] and active galactic nuclei [12] Nebulae. Bright nebulae.

- Advice For Observing Deep-Sky Objects
Deep-sky objects lie beyond our solar system and make great observing targets for those using optical aid under dark skies. Amateur stargazers sometimes refer to them as faint fuzzies. Unlike the nearby planets (which look like little disks through a telescope) or stars (which always look like pinpoints), deep-sky objects are hazy spots in the sky ...
There are a few different types of nebulae, or clouds of gas and dust, that you can observe. There are emission nebulae, which include planetary nebulae, that glow because a star late in its life has puffed off a glowing shell of ionized gas. Then there are reflection nebulae, which are clouds of dust that aren’t glowing themselves but reflecting t...
Not surprisingly, the best place to look for galaxies in the night sky is away from the direction of our own galaxy, the Milky Way. The Milky Way blocks the view of more distant island universes. The closest large spiral to Earth is also the easiest to spot: M31, or the Andromeda Galaxy. M81 and M82 are handy galactic targets for the Northern Hemis...
Open star clusters are young, loosely bound gatherings of stars. One of the most famous open clusters is the Pleiades, found in the constellation Taurus. Because this cluster is so close and large, you can view it best with binoculars or even the unaided eye. A telescope gives you too narrow a view and cuts out members of the cluster. The Beehive i...
Globular clusters are huge, ancient conglomerations of tightly packed stars that orbit in the halo of the Milky Way. The big balls of stars lie much farther away than the open clusters we see. The best known globular cluster for Northern Hemisphere observers, M13, lies in Hercules. This deep-sky target is easy to spot with a small telescope.
To see objects in the deep sky that lie in our Milky Way or even farther, you’ll want a dark skyand binoculars or a telescope. Have patience when tracking down these far-flung gems. Wait for your eyes to grow adapted to the dark. Use averted vision if necessary to pick up the dim fuzzies. A good star chart will help you hop your way across the deep...
They are of two types: intrinsic variables and extrinsic variables. Intrinsic variables change their brightness for physical reasons (contraction, eruption, or expansion). Extrinsic variables are stars that change their brightness due to periodical eclipses caused by another star orbiting around them, or because of star rotation effects.
Most deep sky objects are faint, diffuse and require a telescope to see. They make for spectacular photographs but often appear as little more than a faint smudge of light to your eye, even as seen through a large telescope.
Nov 18, 2021 · In this guide, we’ll explain the differences among nebulae, galaxies, star clusters, and more. After reading about these different deep-sky objects, see if you can locate and identify them with your telescope.
