250mm @ F16, unreal, you'd need two people to carry it, one at each end with walky talky's
F16 would certianly aid in getting planet resolution, perfect scope in a lot of respects for the job. Intreguing to know, assume its a mirror, was custom made ? Ive never heard a scope of these dimensions, not doubting you at all, and if you get a high alt planet in steady conditions with it, well, Mind boggles ! !
Cheers for them specs
