Alex,
Having seen how stacking brings out detail, I have to understand exposure, then relate that to size of stack required to produce the final image.
Equally I need to do some tests to establish the effects of sensor warm up on long exposures.
I will look around at motorised mounts but will stick with photographic lenses for now. The ED82 is a great observing scope and any advance on that should logically be in the direction of 102 - 105.
A workflow for Registax would be very handy in view of my initial experiences. I would also very interested to see the results from a 200mm on a tracking mount as that is the next logical step up for me.
