This central "star" seen in this galaxy is actually the central Star Cluster, though this object is not actually the nucleus of this galaxy....... In recent years, the word "nucleus" has come to mean the tiny solar-system-sized body that is usually found at the very centre of a galaxy. (responsible for Seyfert activity, plasma jets, etc.)
(Neither is one of these nuclear star clusters an extended bulge; bulges are extended spheroidal structures of much greater spatial extent)

As can be seen, the Very Evident central star cluster is still somewhat starlike, even with the Hubble Space Telescope.
Thanks Robert for clearing this up...
If I can't see it in an image it's hard to understand.
The Hubble image puts this all into context clearly.
So thanks for bringing this to our attention.
It's very interesting taking images but finding detailed information is even better as we are learning about the objects we turn our ccds to every year or there abouts.

John.
Look forward to your version John. Binning is definitely the way to go with colour and Ha. When I bin I have some issues which is a gain adjustment I must do to my camera. Would have loved to have pulled in the HII knots just to finish it off.. but there you go...
