I tried both methods Tony and the restacking of the individual images won out, but not buy much. Mind you I've only been imaging widefield with the ED80 so I don't expect much hi-rez of NGC55 that way
Any way here's the final result,
17x300sec (over 3 nights) @ISO800, terribly smokey conditions, transparency maybe 5-6/10, fully processed on the laptop and pretty heavy on the noise filter, so who knows what it is going to look like from your end, probably lots and lots of artifacts
