Raggytash, (post 6:08 a.m.) the instruments used for cosmological searches and imaging (as for new galaxies and black holes) are
wonderful, but designed and useful just for that work. They are not useful for searching for "near" objects within the solar system.

What's more, the training, interest, and protocols of
the high-powered astronomers (cosmologists) who use
those instruments don't focus on such objects as the
planets, even a "new planet" like number 9.
