Description

This target was more difficult than I anticipated, I attempted to spend 6 hours on it but was only able to do about 4 hours and 45 minutes. I imaged from a Bortle 4 zone using the Meade 70mm APO.
This is going to be my last nebula until Summer, as galaxy season is now starting!

I think either 10 hours from a Bortle 4 or 6 hours from a Bortle 1 would make an incredible, clean image.

Some information on this object:
The Jellyfish Nebula appeared 3,000 to 30,000 years ago when a supernova occurred in our galaxy. IC 443 is a beautiful remnant of the explosion that has the shape of a jellyfish.
The Jellyfish nebula is located in the constellation Gemini and is pretty easy to find by using the star- hopping technique.
It is way too faint to be visible with the unaided eye, but you may be able to roughly spot it using a pair of binoculars, only if you are in a location far from light pollution.
Small telescope should reveal the brightest part of the nebula, although the use of a filter is strongly recommended.
