Takahashi 90 mm refractor and color imaging platform


Just can't get a clear night at home (Southern California), so I went to the remote iTelescope.net Australian site, Siding Springs Observatory in NSW for this image of Centaurus A (NGC 5128), a galaxy in the constellation Centaurus. At 10-16 million light years away, Centaurus A is one of the closest galaxies to Earth, and the fifth-brightest in the sky, making it an ideal amateur astronomy target, if you live in the Southern Hemisphere. The center of the galaxy contains a supermassive black hole with a mass equivalent to 55 million solar masses. A collision is suspected responsible for its intense star formation. Models suggest that Centaurus A was a large elliptical galaxy that collided and merged with a smaller spiral galaxy. The image was made with 3 stacked 5 minute exposures on a 90 mm Takahashi refractor and color imaging platform, at midnight local (NSW) time, today.
