NGC 4945, Finalized




NGC 4945, edge on spiral Galaxy in constellation Centaurus.

I was able to finalize this version, since I now have all the needed calibration images, Dark, Bias and Flat frames. This beautiful, large, edge on galaxy is overlooked, since there is two showpieces at neighborhood, M83 and the Centaurus A.

NGC 4945, imaged with a Northern Galactic members remote telescope in Australia,
