This is my first long exposure image with Voyager. Abell 31 is one of the apparently largest PNe in the sky. At the same time it has a very low surface brightness of about 26.9 mag/arc-sec². A shock front is forming in the southeast, where the material of the PN meets interstellar medium.

I really like your widefield view of this object. Most people seem to do tight crops. Your color is just perfect, too. Congratulations.
Great image Mark … congrats !
All the best
Thank you Glenn and Leonardo!
There are not so many PNe that are suitable for shorter focal lengths, but this one is one of them. With my big Newtonian, it would have filled half the field of view.
Fantastic Markus - very nice! I have worked on this one recently also using data from 2017 for Ha but otherwise acquired with Voyager Array.
Your colours and processing are spot on!
Nice job Markus. Beautiful image…
Thank you very much, Roberto and Jon!
