Here a shot of ngc2237 from the italian telescope #1 of the skylive network.

This image is  the raw composition (no post-processing correction at all) of 2 exposures of 900 secs in H, 2x 600 sec H, 1 x 600 for each channel RGB, 2 dark frames ( one of 600 and one of 900 secs ).

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.
