Hi Alun,
That is an interesting spectrum. The hydrogen emission lines that you have picked up will be from HII regions within NGC 2903. Doing a little digging around I see that this galaxy has a high star formation rate. So it makes sense that it has a lot of bright clouds of hydrogen which will be forming stars.
Best wishes,
Andy
