Description

The Pelican Nebula is located just off the “east coast” of the North American Nebula in Cygnus. It is an emission nebula about 1,800 light years away and has an apparent size of about 1 degree by 1 degree in the sky.

This is eight hours of integration over two nights near new moon. The ASI1600MM Pro was at gain 15 and individual exposures were 60 seconds. The telescope was a Stellarvue SV80-3SV riding on a Sky-Watcher EQ6R Pro mount.Image was processed in PixInsight 1.8.7 and final touch up in Photoshop CS 2019.

This was a bit of an experiment. I had been using gain 76 but that limited me to 20 second exposures if I didn't want to clip too many stars. I dropped down to gain 15 and that allowed me to go for 60 seconds and seemed to work out ok.
