A Rough Guide to This Object...

Type: Planetary nebular (?)   
Size: ? light-years  
Apparent size: 12.87'   
Distance: 400 light-years

Notes: The nebula features a central bow shock surrounded by symmetric emission, with a binary star composed of a G-type star and a white dwarf at the centre. This nebula may not be a planetary nebula, but interstellar medium photo-ionised by the passing binary system, leading also to the creation of the bow shock.
