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.

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 6.86.

NGC 1784
NGC 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 Catalog
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.

NGC. New General Catalogue. A list of some 7000 plus deep-sky objects.

The NGC and Beyond
The next big catalog to appear that remains in wide use today was the NGC . The New General Catalogue of Nebulae and Clusters of Stars by John L. E. Dreyer (pronounced "Dryer") appeared in 1888.

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.

The second, known as NGC 5195, is interacting with M51. The outer regions of the two galaxies actually touch each other. M51 is located about 37 million light-years from Earth. Under dark skies, it is an easy target for small telescopes.

Pressing the scroll keys on the Autostar told me further information about the Helix Nebula including its designation as NGC 7293, that it is a planetary nebula, that it is positionally at RA 22:29.6 and Dec. -20 deg. 48 min.
