    Morning Kurt
    All noted and I downloaded the issue in question - very well done and 
    I had some experience with viewing the Apollo 11 mission ( was clouded out for 
    ill-fated Apollo 13 mission) and was able to track the various bits and pieces 
    with Apollo 11 out to about 200,000 miles. At the time it was visual 
    using a 26.5 inch refractor and a 20 inch reflector and they were quite easy 
    visually once I was able to find them. Today with the IMAGING facilities now
    available one can easily do the same with equipment in the 6 inch aperture 
    ( or possibly even less) but visual observing will require considerably larger.
    However I think the chances of observing anything futher out are rapidly 
    diminished by
    the glare from the moon (depending on the phase of the moon) and I would say 
    is very little chance of amateur equipment seeing objects much further out, let 
    very close to the moon.
    Of course observing the trans-lunar trajectory depends very much on predictions 
    available for a particular station. In my case they were supplied by BELLCOM but 
    was a long time ago .
    Do you perhaps know if such ephemerii will be available for stations suitable 
    for viewing such?
    I know there were special efforts made to observe some of the Apollo 11 objects
    impacting the moon but cant recall the exact details but I dont think it was a 
    great success.
    One big snag for me is that its pretty close to my winter season when I go into 
    because of pathetic viewing conditions!
    Best wishes
