< Previous Next >Here is my returning attempt to Cygnus star clouds and North America Nebula. Camera objective is a bit hard to focus and I didn't get satisfying focus. This is a very fun target for camera objectives and easy to track and I even guided it. I did a slight boosting layer for the nebula. H-alpha response really is bad in these cameras.
