IC443 Jellyfish Nebula
Work in Progress
The Jellyfish Nebula is found next to the star “Propus” or Eta Geminorium in the constellation of Gemini. It is around 5000 light years distant (although another source says 1500 ly) and is a supernova remnant. The supernova is thought to have gone off between 3000 and 30 000 years ago.
This image was taken with a William Optics Megrez 90 telescope with a 0.8x focal reducer using an Atik 460EX CCD camera through an Astrodon 3nm Ha filter on 21st January 2014. The exposure time so far is only 6 x 1200s subs due to cloud stopping play. My intention is to get more data in Ha to reduce the noise and also collect some OIII and SII data to make a coloured image as soon as the weather permits -
