Oh, and just one more thing, here is a recent image of this very interesting galaxy, from the Carnegie-Irvine Galaxy Survey:
The outer parts of the faint envelope look like a very difficult observing challenge, even in real dark sky conditions.
[[[ Another dwarf galaxy in the nearby Centaurus Group of galaxies is NGC 5253, which is rather similar to NGC 5102, in that it is a physically small galaxy of type S0
However, NGC 5253 is a pec. galaxy, in that it has recent star formation near its centre (hot & young & massive stars).
(Actually, N5102 also had a star formation episode at one time, as it is very blue for an S0 galaxy.)

Note Added, in a later edit:
Also, to aid in finding this galaxy, I attach a DSS photograph of the field of NGC 5102, which I got from wikisky.org
These wikisky images can be useful for finding galaxies, if the star chart does not do the trick;
however, one must get used to mentally 'editing out' the multitudes of very faint stars that are invisible in the finder, or alternatively, use an image (bitmap) editing program to try to get rid of the really faint stars that can cause confusion.
