NGC 2392, The Eskimo Nebula

Still working on some differential flexure between the guide scope and the imaging scope, but getting very close now. The CI-700 mount tracks like a dream. I'm tempted to turn the guiding off and see what I can get.

This is a poor target choice for this scope/camera combination. (Too small.)
