Centaurus A is a lenticular galaxy about 11 million light-years away in the constellation Centaurus. It is the fifth brightest in the sky, and is one of the closest radio galaxies to Earth, The galaxy shows characteristics of a elliptical galaxy (spherical, older smaller stars), and of a spiral galaxy (dust lane, regions of active star formation) NGC 5128 is easy to spot through a modest telescope. Observing the galaxy's details requires a reasonably large telescope. I imaged this object at the 2010 Texas Star Party (near Fort Davis, Texas). Sky transparency was excellent, seeing was average to good. Clicking the above image will bring up a larger field of view and higher resolution image. |
