This is an awesome hydrogene gas field in Perseus… the name is derived from the peculiar shape which resembles the state California.
Unfortunately it is not visible to the eye even with optics. A DSLR could take the picture, as an example below which is taken with my small TS65APO telescope and the modified Nikon D750, from under the streetlights in Hoegaarden.
Full details on this picture on astrobin.
