Hi and welcome.

There is an international news group where you can ask in languages 
other than English.

You can find the co-ordinates of the bounding box of your object using, 
the functions min_extent and max_extent. Search for them in PovRay help.
The centre of your object should be at the centre of the bounding box.
(Roughly speaking)

But since you are using Blender can you not point it at your object in 
Blender?
