Location (was image taken with remote scope?): Cartagena, Spain.

Image Description and Details: CTA1 is a large and very faint supernova remnant in the constellation Cepheus. CTA is short for the California Institute of Technology (Cal-Tech) observatory list A, the first list of radio sources generated at the university in 1960. It is generally referred to as G119.5+10.2 as a whole, but the entire remnant also includes component sections cataloged as G119.5+9.8 and 10.0 The supernova explosion is thought to have occurred approximately 10,000 years ago and is estimated to be about 4600 light years from Earth. The region is a very dim target and is rarely imaged.

The bright object on the right of center of the image is the planetary nebula NGC 40. This is a very striking object exhibiting bipolar symmetry, sometimes called the Bowtie Nebula.
