It's been a while since I chose a planetary nebula, but this image comes with an added extra I couldn't resist. A mixture of the showpiece and the obscure.

Clear and dark skies are needed for Owen's challenge this month. A faint group of galaxies in a single high power field of view. A physical group or not?
