Some nice detail JJ but as you say the noise is a worry. Remember though this is quite faint and such short exposures will always struggle to get on top of the faint signal you have to work with.
I think I would have been looking at ISO 800 as a minimum for this sort of image on such a faint target. Noise can always be controlled but signal can only be lifted with exposure and ISO.
Don't despair yet. This camera may be different from what you are used to and some changes of habit might be required to get the results you are after. Keep at it.
