**** ABOUT THIS IMAGE ****

This unique and extremely deep colour image, compiled from nearly 20hrs of exposure with just a 6"
telescope, was taken from a very dark sky in remote Australia. The image reveals the full outer
halo of the perculiar radio galaxy Centaurus A (NGC 5128) in Centaurus including faint polar
extensions extending from the top and bottom of the galaxy running diagonally. Also evident in this
image is the extensive but extremely faint Milky Way nebulosity and dust known as "Galactic Cirrus"
or "Integrated Flux" that permeates this entire region. Galactic Cirrus material lies just above
the plane of our galaxy and is lit by the light of The Milky Way as a whole but due to its extreme
faintness at 27mag/sq arc sec, is seldom seen in images, it is visible as faint patches
of dusty looking nebulosity all over the image. The Cirrus nebulosity around Centaurus A is some of
the faintest in the sky and is well below the natural sky brightness. Countless distant background
galaxies of all shapes and sizes can be found scattered all over the field of view as well.

Here are other image views that showcase various aspects of this amazing southern galaxy!
