A luminance filter only image of Centaurus A incorporating 90 minutes of data taken in May 2010. The hope is to add more luminance and color data next year when it is briefly availabe again on my low southern horizon.

NGC5128 (Centaurus A) is located in the direction of the Constellation Centaurus at an approximate distance of 11-13 Million Light-Years. It is a very peculiar galaxy and seems to have an intermediate morphology exhibiting both lenticular (elliptical) and spiral galaxy structures. A supermassive black hole at its center contains over 200 million solar masses of material ejecting relativistic, strong radio source emissions along its polar axes. The present morphology seems to have been the result of an elliptical galaxy ingesting a large spiral galaxy in the last 200-700 million years. The superimposed dust lane across its face exhibits many star forming regions. There are many globular cluster structures in the bright halo, some of which could be the cores of dwarf galaxies absorbed in the past. It is the second strongest radio source to Cygnus A, and has a strong radio wave emitting core only 10 Light-Days across. It is the fifth brightest galaxy in the nighttime sky.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
