I too never knew the planetary nebula was located nearby. That's one of the fun aspects of narrow band imaging, we often find planetary nebula that we didn't know were there. Even the faint ones pop out. This planetary nebula is exceptional in that NII emission dominates. Usually they look teal because the OIII emission dominates.
