IC443 - Jellyfish Nebula

Here is another urban image taken from my driveway in the light polluted skies of Bedford. It is an image if IC443 known as the Jellyfish Nebula. This image uses an Optolong L-eNhance filter to make the target more visible under urban light pollution.

According to Wikipedia - IC 443 (also known as the Jellyfish Nebula and Sharpless 248 (Sh2-248)) is a galactic supernova remnant (SNR) in the constellation Gemini. On the plane of the sky, it is located near the star Eta Geminorum. Its distance is roughly 5,000 light years from Earth.
IC 443 may be the remains of a supernova that occurred 3,000 - 30,000 years ago. The same supernova event likely created the neutron star CXOU J061705.3+222127, the collapsed remnant of the stellar core. IC 443 is one of the best-studied cases of supernova remnants interacting with surrounding molecular clouds.

I made three attempts at processing this one. There is a lot of detail in the "head" of the jellyfish that I had quite a bit of difficulty hanging on to throughout the processing. As usual click on the image to see a higher resolution version and click again to return to this page.
