Interesting hot topic at the moment. Many builders of scopes with big,very thin mirrors are making sure to support the mirror on its centre of gravity. Usually with +/- 45 degree points or a cable sling. http://www.cruxis.com/scope/mirroredgecalculator.htm

But with this thickness of mirror any solution would probably be OK. That is, simple +/-45 points, seatbelt sling, or RTV-ing the cell directly to the mirror(if it doesn't wobble).
