Thanks Bogie. Glad you enjoyed the tour of the Observatory, even if it is a little unfinished As you can see, there are now so many wonderful objects available to us, thanks to people like you, that there are times when drawing a map is more like doing a montage - and a lot of fun

That vertical scope might just be the one I'm looking for, and will save me oodles of time trying to draw the thing, though I will have to see what I can do about carving or engraving the name on the side of its barrel. It seems almost a shame to have it covered by the dome, but it has to be that way because of the predators in the sky. I'll see what I can do about making the glass just a little more transparent.
