If you define a macro, you can use the macro's name, with it's 
parameters) by itself.
When you #declare an object, you need an object{MyObject} construction.
When you #declare a sky_sphere, you need to use sky_sphere{MySkySphere}
Just the name of the object, sky_sphere, texture, pigment, material,... 
is not enough.
