Most don’t think of the Gemini Twins as a haven for deep-sky objects. Yet this is a misconception. IC 443 (aka- Jellyfish) is a fascinating object and well suited for imaging. At 5,000 ly from Earth, it’s a supernova remnant, SNR, that exploded between 30,000 to 35,000 years ago. As with most SNRs, there is a fast rotating neutron star at the center. It is wider than the full moon and about 70 ly across. This image was taken with an FC100D refractor at f7.4 and 740mm. This is a great NB object and rich in Ha, OIII, and Sii. The total exposure was eight hours and processed in Pixiinsight.
