Image of IC443 by Graham Caller

Another excellent image by our member Graham Caller. This time it’s IC443 also called the Jellyfish Nebula.  It’s a supernova remnant in the constellation of Gemini.

Click the thumbnail image above for a larger version, though note that this has been reduced in resolution for the web.  The original is even more impressive.

Graham comments:

Last week was IC443 week. A couple of clear nights and I grabbed 8 hours worth of 15mins subs. Topped up this week with another 2.5 hours to improve the signal to noise ratio further.

Oh! this was taken using an Ha filter.

We are hoping Graham will give us a lecture in the future, on his astroimaging techniques.
