Jelly Fish Nebula

 About

Here are all Capture Details for this extensive project!

The Jellyfish Nebula is a well known object among amateur astronomers. It is especially noted for it's obvious photographic nature containing a lot of blue and red. It is also rich in hydrogen alpha (Ha) and sulfur iii (Sii) and needs more capture time for Oxygen iii (Oiii.)

IC443 lies on the foot of one of the twins of the constellation Gemini, Castor between the bright stars Tejat and Propus.

Both Ha and Sii have wavelengths in the Red spectrum while Oiii is aligned to the Blue spectrum.  

Some Light Science

The Jellyfish Nebula, or (Index Catalogue) IC 443, is the remnant of a supernova lying a relatively close distance in astronomical terms of 5,000 light years from Earth. IC 443 may be the remains of a supernova that occurred 3,000 - 30,000 years ago. IC 443 is one of the best-studied cases of supernova remnants interacting with surrounding molecular clouds. IC 444 is a nebulous region near Tejat or μ Gem

SHO

Commonly known as the Hubble Palette where Siii is mapped the the Red channel; Ha to the Green channel; Oiii to the Blue channel.
