I included the X_TextureMaps files for use by anyone who can and may desire to make better materials with them.  As the names may imply there is a cavity map, and 2 edge maps made with different settings.  Lastly there is an equirectangular environment texture I used for reflections in my preview renders.  I made it very similar others you may have seen for material balls.  Hope you find good use and enjoyment from this and any of my other models.  A minimal amount of rigging has been done so that it will rotate to point to the Pointer Empty.  The lid and it's chain should rotate opposite the telescope so that it seems to hang naturally.
