Clearly, hanging multiple mirrors isn't rocket science, but there's one trick that pops up in the images here. When grouped together, the mirrors tend to look best if they are very similar — as in Image 1 — or, as in Image 2, markedly different. Especially if you opt for a pair, they'll look best if they are identical (Image 10) or opposite (Image 5).
(And, if you're interested, check out the telescope's beryllium mirrors here.)
