I see you re-added this image to Yerkes Observatory. Usage does not seem to meet Wikipdias WP:NONFREE requirements, namely it is not being used re:

Film and television screen shots: For critical commentary and discussion of the cinema and television.

It is being used to decorate/illustrate what an observatory looks like. The Licensing tag does not cover this usage. You need to provide some fair use rational to keep this image from being deleted. 75.196.250.129
