The Jellyfish Nebula (starless and with stars). This nebula, also known as IC 443, is a supernova remnant. The event led to the formation of a neutron star. The Jellyfish is formed by the impact of the interstellar blast wave with a molecular cloud. The nebula is in a part of the sky that has many stars as seen from Earth. It is hard to process the image and see the true shape of the cloud in many images. Removing the stars shows the cloud's features in more detail. It's remarkable, considering the extra detail in the nebula, that all I did was remove the stars. There is no other extra processing.The second image is the original image with stars.
The trials, tribulations and small triumphs of a Charlotte, NC astronomer imaging under Bortle 8/9 skies.
