On this picture you can see the difference by using more exposures to compose the very same field of view of the latest post.

This picture is a work in progress, i will add a lot of more exposures next days. This is composed by 13×180 sec L filter, 7×180 of R, G, B filters, 4x dark frame at 180 sec, for a total of  a little less than 2 hours of total exposure time.
