Jellyfish Nebula (IC 443)

Overview

IC 443, also commonly called the Jellyfish Nebula is a supernova remnant (SNR) located in the constellation Gemini. It’s estimated that the nova took place between 3,000 and 30,000 years ago and that this is likely tied to the neutron star CXOU J061705.3+222127. From our current location the target is roughly 5,000 lightyears from Earth.

The image at the top was developed using 33 hrs our integration time mapped to an HSO narrowband pallette. Below you will be able to also find an HaHOO version along with starless and annotated versions as well.

I’m fascinated with SNRs as imaging targets. There is a number in the night sky that can be imaged with a handful in the northern hemisphere that are visible. A personal goal of mine is to spend time on each SNR that can be shot from my location and using Telescope Live’s southern hemisphere observatories to image those below the border.
