Cosmic Jellyfish

IC443, commonly referred to as the Jellyfish Nebula can be seen swimming to the right of the bright yellow star Propus in this image.


William Optics 80mm with 0.8x reducer
Canon 300D modified
Autoguided EQ6
12 x 10 minute exposures @ ISO800
I took the image last night (8th March 2010) in a brief 2 hour period of clear skies. I plan to take several more hours to bring out the depth of the surrounding nebulosity to the East of the Jellyfish.
The image processing consisted of dark (3), flat (10) and bias (10) frame calibration, Extended Addition and Digital Development (DDP) stretch. The image was tweaked for noise (NeatImage) and colour balance in Photoshop.
