NGC 6891 and NGC 6905
Delphinus is a small constellation in the equatorial region of the sky, with a distinctive kite-shape. Although small in size, Delphinus contains a variety of deep sky objects for backyard telescopes.


NGC
The acronym NGC stands for "New General Catalogue" and usually precedes a number in the catalogue, like NGC 4258 for example. The catalogue refers to objects which are extended and distinctly non-star like in nature.

NGC 6193: The "Four-In-One" Cluster

In most planetaries (like the famous Cat's Eye nebula, and the less famous but also cool NGC 6826) the outer halo slams into material floating in interstellar space, causing it to get all clumpy or form a bright rim as the surrounding matter gets plowed up.

NGC 4755 is located at R.A.: 12:53.6 and Dec: -60:20
This cluster was discovered by Nicolas Louis de Lacaille from an observing station in South Africa during his stay there from 1751 to 1752.

NGC 4889 is a member of the Coma Galaxy Cluster, which lies about 300 million light-years away. But the quasar 3C 273 is 2 billion light-years away. While a little fainter than NGC 4889, it should be barely visible in your 5-inch if you have a dark sky.

NGC 7129 is a young compact star forming region which displays an unusual patchwork of colorful nebulosity and bright stars contrasted against the dust clouds of the Milky Way.

NGC 604 is even larger than the Tarantula nebula at about 1,300 light-years across, although it contains slightly fewer stars. It is one of the largest H II regions in the Local Group.

The New General Catalog (NGC) is a list of over 13,000 deep-sky celestial objects, such as galaxies, globular clusters and nebulae. It was developed in 1888 by the astronomer J.L.E. Dreyer, and often celestial objects are referred to by their list number, e.g.

It also contains many star clusters, such as Messier 30, as well as the elliptical galaxy NGC 7103 and the spiral galaxy NGC 6907. The Capricornids meteor shower is also a feature of this constellation, peaking annually around July 30th when up to 30 meteors per hour can be seen in the night sky.

He called it the New General Catalogue. More information was added in the 20 next years such that its listings reached close to 15,000 objects. Astronomers refer to galaxies and nebulae by their NGC numbers. For example, the Crab Nebula is called NGC1952.

In contrast, the Andromeda galaxy, which is also known as M31 and as NGC 224, is much small on the sky, less than three degrees in length, which is larger than the Moon or the Sun. It can only be seen when the sky is very clear, and generally only the inner bulge of the galaxy is visible.
