Description

A group of galaxies in Centaurus, a region full of nice objects to capture. The main focus is obviously NGC 4945, a typical barred spiral galaxy. The second one that comes out quite nice is the NGC 4976, which turns out to be a peculiar elliptic galaxy, some explanation can be found in Wikipedia, but it seems that an small percentage of them are designated as of peculiar shape, like this one.

The third one is the little ESO 219 - 28, just next to a star, a yellowish one, below the big blue one. Finally, in the image it can be seen, the glimpse of ESO 219 - 25, at the bottom left of NGC 4945, quite tiny, and its major axis nearly perpendicular to the one of 4945.

This was a sort of short capture for such faint objects but even so, it shows some nice details.
