Hi Dunk & Russell,
The thing that seems to change the duration of the stacking is using the median sigma clipping rather than just average or median processing in the settings. And then if you tick the Drizzle option, that adds a huge amount of time to the processing. I've now got 16GB of RAM, and I started a stack last night at 10 pm, with median sigma clipping and drizzle, just to see if it would be better. The stack still has over an hour to run.:eye pop: As suggested, I've not got the bias frames in this stack, so we'll see if that helps.
If I just use the "average" or "median" options in the settings box, its only an hour long too. I just thought the drizzle option would help with the stacking artefact.
I've spent this morning updating DSS to version 3.3.4 through wineskin (a complex process too) and the yahoo forum on DSS says that this version is configured for the Canon 70D, so I assume that earlier versions are not compatible with this camera, and maybe that is the source of my difficulties.
Its a long and winding road, this astrophotography thing - I'm learning a lot, including control of frustration. Thanks again for the tips.
Luke
