Here is an example of some data I have been working on today. I took a single 60 second sub and replicated it 9 times and stacked the 10 files. The result is on the left. The images are four times the original size and strtched exactly the same.

On the right is the result of stacking 10 different subs of the same duration. As the files were different I could do some data rejection to get rid of the effects of defects in the CCD chip and other random noise.
