[Omaroo (Chris Malikoff)]

So that means, David, that you should have to own the equipment you use to take a photograph? What if I were to take my OTA and camera, and go to a commercial observatory to use one of their mounts because I don't have a guided mount? Is that not kosher?

Maybe it should be worded such that it is expected that you are present, in person, when the equipment - whatever and wherever it is - is used, and that it is under your immediate control. The raw image data collected would then be required to be processed by you personally.
