Description

Angular size - 134''

Small planetary nebula in Delphinus constellation. With low surface brightness it's quite difficult object for photography. Some signal in green channel and significant in blue makes it a little cyan on the final photo :)
Small central star is with more "electric blue" color.

Below small galaxy PGC 65491 with magnitude close to 16 mag and 200 million ly distance
