Alv 3
Alv 3 is an obscure irregular likely planetary nebula in the constellation Taurus, discovered by Portuguese astronomer Filipe Alves in 2011. Spectroscopic analysis will help confirm if this is a true planetary nebula, or alternatively ionised interstellar medium. At the centre of the nebula is the unusually young and hot white dwarf WD 0340+103.
I believe that this is the first amateur photograph of this target.
