NGC2440 is strange indeed I wonder what solar winds created that arrangement.
I do like the ghost of Jupiter, why is it named that as it bears no resemblance to what Jupiter looks like.

Thanks Bill.
NGC 2440 is one of the hottest white dwarfs 219000K surf temp and does have a faint halo around the whole object. There is an inner torus and multi polar components difficult to pick out shown in the attachment.
I think we should have an object renaming program, but it's history I suppose. With CCD's it's not like looking through a telescope at a hazy blob with averted vision - we get the full detail.
Thanks everyone for comments.
Regards, John.
