Kn26 - a rare quadrupolar planetary nebula

About this image

Kn26 was discovered by Austrian amateur astronomer Matthias Kronberger in 2006, although it wasn't spectroscopically confirmed as a planetary nebula until 2011.
In 2012 it was established that it was a new member of the very small sub-class of quadrupolar planetary nebulae (https://www.aanda.org/articles/aa/pdf/2013/03/aa20592-12.pdf).
Almost all of the detailed structure is found in the Ha emission. 12 hours of OIII data only revealed the central core with no structural detail.
Image captured on my remote dual rig at Fregenal de la Sierra in Spain between 12-20 August 2021.
