Notes
The Jellyfish Nebula is a galactic supernova remnant (i.e. the remains of an exploded star), believed to have been created by a supernova explosion between 3000 to 30000 years ago. This supernova also created a neutron star which is the collapsed remnant of the exploded star's core. (A teaspoon of neutron star material weighs about a billion tons!)
This is a recapture of an old DSO that I last imaged in 2022. This time around, I used a longer focal length telescope (effectively higher "magnification") and a camera with a larger APS-C sized sensor. These images were captured over 4 nights spread through January 2024. I was able to make this picture significantly brigher due to the higher SNR and it shows in the surface of the nebula. Some folks rotate this image to further the jellyfish-like appearance, but I personally prefer this composition with the very bright star at the bottom.
