Jones-Emberson 1

Image Description and Details :

Jones-Emberson 1, a.k.a the Headphone Nebula, is a northern planetary nebula. It is also catalogued as PK 164+31.1. It is located about 1600 light years away in Lynx. The red and green glows are mainly due to emissions from hydrogen and oxygen atoms, respectively. The nebula’s brightness is listed as magnitude 14.1, but it is relatively large, so the light is spread out and it has a very low surface brightness.

This image includes galaxies that lie millions of light years away, thousands of times further away than the nebula. Look for streaks and smudges that look obviously different from the sharper, rounder stars.

Acquisition, focusing, guiding and control of Paramount MX mount with TheSkyX. Focus with Optec DirectSync motor and controller. Automation with CCDCommander. Equipment control with PrimaLuce Labs Eagle 3 Pro computer. All pre-processing and processing in PixInsight. Acquired from my SkyShed in Guelph. Minimal moonlight, above average transparency and average or better seeing. Data acquired March 21-April 13, 2021.
