Nicola,
You might consider the free SGBNR grain and noise reduction tool from
Pleiades-Astrophoto to reduce your grainyness in the shot. I had a similar
picture at a similar focal length (210mm) piggybacked on a 12" SCTon Kodak
RG400 (but 30 min at f5.6) and you can see the before:

and after (I rotated it, but same photo) the noise reduction application
here:
