-In simple terms, any celestial object or a group of celestial objects that is / are not a part of the solar system or individual star is known as a [Deep Sky Object](#deep-sky-objects) (DSO). They're objects of interest among the astronomy community and are treated differently, one of the reasons being that while [tracking](../../astrophotography/tracking.html) the object using an [equatorial](../celestial%20sphere/equatorial.html) mount, you only need to move the mount in the RA axis to make sure that the object is always in frame. The list of DSOs includes but not limited to:
