Headphone Nebula (Jones-Emberson 1) in Lynx
This very faint planetary nebula with a low surface brightness, is in the constellation Lynx. It lies at a distance of around 1600 lightyears, and was only discovered in 1939.
It is composed of the outer layers of a sun-like star grown to be a red giant, successively shed over time. The remnant white dwarf star can be seen, shining dimly at the centre.
This image is the result of 7.5h of narrowband (Hydrogen-alpha and Oxygen-III) data capture from Horsham, over 4 evenings in February 2022. Ha has been mapped to red and OIII to blue.
A ZWO ASI2600MM Pro monochrome camera was used, through an 8-inch Teleskop-Service Ritchey-Chretien Cassegrain reflector.
