Paddy, that's a very good observation of NGC 7479.

It is always nice to be able to see, by eye, the morphology that we see in photographs of a galaxy.

I can't say that I ever saw this galaxy when I was in my prime for visual observation.(not a regular visual observer at present.....)

The "core" is a mild example of a circumnuclear burst of star formation that is caused by gas funnelling inwards along the bar of a galaxy.
A prominent example of a such a "starburst nucleus" is in the barred spiral NGC 1097 - there is a tight central ring of HII regions which may be detectable by eye.

The two main arms of N7479 are very different from each other.....can you see this visually?

cheers,
Robert
