Thanks for all the positive comments. I feel extremely chuffed!
Yes, I did realise Titan was in the frame (admittedly, more by accident than judgement!). Almost requires some averted vision to see it! I even tried to point it out to my daughter when I was processing, but she couldn't see what I was getting at (she is only 5, bless - start them early).
Geoff - the only filter used for this is the IR filter that is fitted to the camera as standard. Apart from a nebula filter, I don't actually own any filters - would you recommend one for this (it's a colour camera)?
Brian - yes, I do need more images in the stack, but this is where my inexperience with Registax comes in. The AVI was about 3 mins in total at 9fps, but the back end of the AVI is pretty grim thanks to aircraft passing by which made the whole thing go completely out of focus. I haven't worked out how to exclude the worst parts from the stack (or I am not confident that this has happened). The final image of a few hundred stacked frames seemed worse than the above, which is actually the reference image formed by stacking a few tens of the best frames. I think I need to sit down with Registax again and have another bash.
Anyway, thanks for looking and all your comments.
