NGC 5128 - Centaurus A - and the small group of galaxies around NGC 5090 - Widefield

Object description:

NGC 5128, Centaurus A, is one of the most extraordinary galaxies in the southern sky, both in view and in its multiple structures. At a distance of "only" 11 million light-years, it is very close to the solar system and therefore one of the best studied galaxies outside the local group. Together with Messier 83, Centaurus A forms the center of a close galaxy group outside the local group.

A detailed description of Centarus A and higher resolution images can be seen here and here.
NGC 5090is an elliptical galaxy with an active Hubble-type E2 galactic nucleus. It has an estimated diameter of 125,000 light-years and is located at a distance of about 145 million light-years from the solar system. Together with NGC 5091 it forms an interacting pair of galaxies. Nearby NGC 5090 are two other galaxies designated NGC 5090 A and NGC 5090 B. Other galaxies in this group are NGC 5082 and NGC 5086. NGC 5090 was discovered by John Herschel on June 3, 1834.
