PN G136.7+61.9 is a planetary nebula in Ursa Major.

PN G136.7+61.9 is extremely faint planetary nebula with size of about 7 arcminute that was discovered in 2013 by analysing data from the SDSS spectroscopic survey. The Sloan Digital Sky Survey or SDSS is a major multi-spectral imaging and spectroscopic redshift survey using a dedicated 2.5m wide-angle optical telescope at Apache Point Observatory in New Mexico, United States. The project was named after the Alfred P. Sloan Foundation, which contributed significant funding.

This is the first colour image ever taken of PN G136.7+61.9 planetary nebula. In appearance, as well as low surface brightness, this planetary nebula could be called "Night Owl Nebula".

This image taken over several nights in May 2021.
