Image below is of NGC 2392, the Eskimo Nebula in constellation Gemini. The one from the Hubble is admittedly just a tad bit better.

Image from last night, Feb 5 after 11 pm, 12 deg. F, no wind, transparency was good, and turbulence was better than usual, about 6/10. All images from Nexstar11, F3.3 focal reducer, and Stellacam II video camera, (4 second integration, 9/14 gain). 30 frames aligned, dark subtracted, flat field corrected, aligned, stacked, and enhanced with Registax4.
