Nice work Leonardo. You've captured some good detail in the brighter
parts of the galaxies. As a general rule stacking more frames will
allow you to go deeper to bring out some of the detail in the darker
areas, and will reduce the impact of noise on the image, up to a
practical limit. What that limit is depends very much on your
camera. You need to experiment. Looks like you don't have an issue
with guiding though - its very good.
Cheers
Greg
