At the center of this image is SH2-249, an emission nebula in Gemini. At the top right, is IC443, which you will also see featured elsewhere in my collection of photos. IC 443, the Jellyfish Nebula, is a Galactic supernova remnant, in the constellation Gemini, that occurred 8,000 years ago. It is one of the best studied cases of supernova remnants, interacting with surrounding molecular clouds. IC 443 spans about 65 light-years at an estimated distance of 5,000 light-years. The large expanse, at the center, is at a distance of 5200 light years. This image is about 3 hours of exposure, split between h-alpha and RGB filtered sequences. The telescope is my TAK FSQ-106, using an SBIG STL-11000 CCD camera. It all sits on top of a Paramount computer driven platform. These images were collected April 23 and April 25, 2009 from my backyard observatory. Click on the image to see it at a larger scale.
