To be strictly accurate (and less confusing!), QX Pup
is the embedded, invisible Mira inside of the
bipolar nebula OH 231.8+4.2.
As Moran wrote, a good description of the system
(nebula and Mira) with a high-quality IR color
composite can be found at:

It is very pretty, and reminds me of other bipolar
nebulae like GGD27. Our JHK color composite
of GGD27 can be seen at:
