Several nebulae in the constellation Orion commonly called deep-sky objects. A deep-sky object (DSO) is any astronomical object that is not an individual star or Solar System object (such as Sun, Moon, planet, comet, etc.).

Mar 15, 2010 · Deep-sky objects are celestial objects that exist outside our solar system. Three major types of deep-sky objects are nebulae, star clusters, and galaxies.

Observing list of 650 best deep-sky objects, with thumbnail images and some basic information. The list is sorted by constellation and magnitude (sorting by name is also available). List includes all Messier, Herschel, Caldwell, SAC's best of NGC, and ~150 additional DSOs.

Feb 28, 2025 · Deep-sky objects (DSO) are celestial objects that lie outside the Solar System. They comprise galaxies, planetary nebulae, and star clusters. Deep-sky objects appear as fuzzy spots to the naked eye and start to take shape when looked at through binoculars or a telescope.

Mar 7, 2024 · We'll introduce you to beginner-friendly deep-sky targets — galaxies, nebulae, and star clusters. No need for fancy equipment: all objects in our list can be observed with binoculars, and some are even visible to the naked eye.

Deep sky objects. Deep sky objects (DSO) are those beyond our solar system - stars, galaxies, nebulae, and star clusters. For a list of the constellations to find DSO objects, see the 88 Constellations of the Night Sky. What makes a "best" DSO? …

Deep Sky Objects, as listed on this page, refer to galaxies and nebulae (with their associated stars). Star clusters (like the Pleiades and Hyades), are also included. Most named stars, if not surrounded by nebulae, are described in the "Special stars" section of the IAU Constellation page.

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.

Learn the latest tricks for finding and imaging deep sky objects from nearby star clusters and nebulae to distant galaxies.

The category labelled “deep sky” comprises every astronomical object that is beyond our solar system. Generally, these objects in the depths of space are not visible to the naked eye, but the brightest of them can be seen with a small telescope or even with quality binoculars.
