The proof of all this will be in the images presented no matter what approach was taken. Then the better images will show the best way to achieve them. If that is traditional LRGB 5-15 minute subs 1x1 binned and 2x2 binned colour at 5-15 minute subs or very short stacked.

In my experience even reliable 60 second unguided image is difficult even with high end mounts. Star elongation sets in fast at anything above 500mm focal length.

But autoguided 60 second images are relatively "easy" ( I don't know that anything is "easy" in tracking!).

The Sony ICX CCD cameras required a different approach to the usual for optimal results. Dark subtraction often visibly added noise.

Time will tell meanwhile its fun to speculate on what might be. So no need for heated discussions on mere speculations and predictions.

The images will speak for themselves.

Greg.
