For time lapse stuff I think the best way is as mentioned above, to do it all in post processing and take advantage of the resolution of the sensor, since it doesn't require any extra equipment. You just need to make sure everything fits in the frame of the UWA lens. Time lapse videos that are taken on a sliding rail have a different effect and can't really be replicated with post processing since the point of view actually changes.

I'm working on an apparatus to match the rotation of the Earth so I can take longer exposures of the stars and it could do this too, but it's a lot more work than post processing!
