Great to see your enthusiasm, Dave. From what I have read, however, an element of caution? I don't think building a 24" truss reflector is a simple matter of scaling up what you have seen in a GSO 12" solid tube reflector. Apologies if I'm stating the bleedin' obvious, but I think there would be a lot of reading, designing and testing needed, as well as collecting the accumulated wisdom of the ATMers on the site here and elsewhere. Mirror cell design, flexure, altitude bearing size, balance, mirror cooling all come to mind as issues that are not simply scalable from a smaller scope? But again, this is what I have read rather than done! Best of luck and we look forward to seeing the result evolve.
