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

This image is a three-colour composite, this time reproduced from one blue (B), one green-yellow (V) and one red (R) exposure, obtained with FORS1 at ANTU in the morning of March 29, 1999. The field size is again 6.8×6.
6193: The "Four-In-One" Cluster
By Brian Ventrudo
This young star cluster in the southern skies was born just 3 million years ago from gas and dust compressed by a nearby supernova explosion.
NGC 253, a starburst galaxy
On the left, you see an image of the spiral galaxy NGC 253, taken with a ground-based telescope. The galaxy is located about 8 million light-years away in the constellation Sculptor.

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.
1784 is a fairly unremarkable barred-spiral galaxy at first glance. However, studying even the seemingly common may reveal unique aspects that help forward our understanding of the universe.
NGC 4414, a typical spiral galaxy in the constellation Coma Berenices, is about 17,000 parsecs in diameter and approximately 20 million parsecs distant.

NGC 6231: A fine open cluster, composed of over one hundred stars in a compact 15' area. It actually lies on another spiral arm of our galaxy, closer to the galactic center.
7603 is a Seyfert galaxy with disturbed form and an apparent companion along an extended arm or tail. 7603 has a redshift of 8700 km/s and the companion is at 17,000 km/s.
New General Catalogue -- A catalogue of 7,840 nebulae, star clusters, and galaxies that was published in 1888 by John Dreyer.
An acronym for New General Catalog of Nebulae and Clusters of Stars, first compiled in 1888 by Danish astronomer J.L.E. Dreyer at Armagh Observatory, Ireland. Today the catalog contains 7840 deep-sky objects.

1313 is a barred spiral galaxy 15 million light years away in the Southern Hemisphere constellation of Reticulum.
NGC 253, a nearly edge-on spiral galaxy (type Sc) in the constellation Sculptor. NGC 253 lies about 8 million light years away.
6333 or Messier 9 is a globular cluster, one of the nearest ones to the centre of the Milky Way. It is about 25,800 light-years distant from Earth. 6254 or Messier 10 is another globular cluster about 14,300 light-years distant.
NGC 613 is a barred spiral galaxy in the southern constellation Sculptor. The galaxy is inclined by 32° and, contrary to most barred spirals, has many arms that give it a tentacular appearance.
