Stacking experiment

I know this is similar to the previous shot from this location, however I thought it might be of interest as a comparison. This shot has been put together using a free star stacking program called Sequator, it is the first time I have used it and I am quite impressed. The other shot is done from a single image and it is interesting to see the difference in noise.

This was only stacked using 4 images as I was not shooting with the program in mind but it will quite happily stack 20 images.

This is 4x 20sec exposures @ f4 ISO6400
