First up is one of the first objects I imaged with the 14" scope back when I didn't have color capability, NGC 7538. Thanks to all the moonlight I was unable to go as deep as I'd have liked so the large faint nebulosity around it is mostly missing. You may barely detect a dark nebula in the upper right corner for instance. That is LDN 1225. Adding H-alpha would help but the skies never cooperated. It is about 9000+ light years away and is in a huge HII complex in Cassiopeia. The Bubble Nebula is part of this complex as well. HII regions are where stars are currently being created in our galaxy. This one is very similar in size to the far nearer and more famous complex that occupies much of Orion and includes the Orion Nebula.

Some call this nebula the "The Ghost Nebula" with the two bright stars in it being the eyes. I can't see it myself no matter how I rotate the image.
