IC 443 CCD Collaboration - Last Update 01/04/2004

Introduction

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.

Please use the following finder image to help orient your camera properly.

Strategy

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).

Status

H Alpha

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

The individual data frames are available on these sites:

RGB
We have no RGB data so if you would like to start please do! See the finder image above so you get the right orientation for your camera, and try to image at around 5-6 arc-seconds/pixel.
