When imaged under dark sky with wide band LRGB filters there is plenty of small galaxies in the background. But imaged under light polluted sky with narrowband filters galaxies are cut off.

This planetary nebula does have also a nickname – Headphone nebula. And is also known at Perek-Kohoutek catalogue as PK 164+31.1

Clear skies!
