IC443, commonly known as the Jellyfish Nebula, is a Supernova remnant, from Crayford skies is really only visible if imaging using narrowband filters.

Imaging:

Ha filters work the best but it will also show up in SII filters, it is invisible in an OIII filter.

The California Nebula – NGC1499

The California Nebula (NGC 1499) is an emission nebula located in the constellation Perseus. It is so named because it appears to resemble the outline of the US State of California. It is almost 2.5° long on the sky and, because of its very low surface brightness, it is extremely difficult to observe visually. It can be observed with a H-Beta filter (isolates the H-Beta line at 486 nm) in a rich-field telescope under dark skies. It lies at a distance of about 1,000 light years from Earth.
The California Nebula was discovered by E. E. Barnard in 1884.
