NGC 1365 is a favourite of mine, so since I now have the gear I dreamed of, I am doing the targets I always wanted to. Shame the SN is gone now 
Anyway, 200 secs... pretty paltry, but again it was only a test to see how a GX responds to H-a. The faint arms structure/halo is JUST starting to show. More exposure will benefit.

That's not bad Lewis but to see more than the reverse S shape I reckon you need about 8-10 hours to do this one justice.
