The weather for the astrophotography season has been pretty dire the past year and has not given many good nights for deep sky. I hear the same comments resonating around the astro community for those people in the UK.

However, I did manage to get some data for a target known as the Jellyfish Nebula, designated IC 443 and Sh2-248. It is a large supernova remnant of approximately 70 light years across that lies newar the star Eta Geminorum.

Image data acquired using a TS100 APO Quad with an Atik 460 EXM with a 3nm Ha filter all mounted on my EQ8 in the observatory. 9 hours total integration consisting of 18 x 1800s sub-exposures.

Stacking and processing was with PixInsight with some final touches with Adobe Photoshop CS.

This image was European astronomy picture of the day (EAPOD) on the 17th January 2017. You can see it here
