Description

Jones-Emberson 1 (PK 164+31.1), also known as the Headphone Nebula, is a 14th magnitude planetary nebula in the constellation Lynx at a distance of 1600 light years.
It is a larger planetary with low surface brightness. The 16.8-magnitude central star is a very blue white dwarf but it's practically not visible on this picture due the stars reduction process done to show better the nebula structure.

Again fighting with another planetary nebula.
This time was a little bit more that 60 hours of integration time, with the idea to show these dim structures around and have enough data to drizzle and crop the picture on my 'little' 10"......
