The first object under consideration by the members of the Yahoo group CCDCollab is a supernova remnant known as IC 443. It is in the constellation Gemini and has a size of about 50 arc-minutes. Some people call it the "Jellyfish nebula" based on its shape.

Pretty simple - grab lots of H Alpha data, followed by RGB data. We are using a pixel scale of around 3 arc-seconds/pixel for the H Alpha data, and most likely around 6 arc-seconds/pixel for the RGB (binning 2x2 for our camera/telescope combinations).
This image by Paul Kanevsky represents the combination of the data collected so far. Please compare to the previous attempts listed above and you'll see we've pulled out some impressive detail.
A combination of all the available data is availabe at pk.darkhorizons.org/images/collab/collab5.zip
