Back when I started I would come up with ways to make a mirror rather than buy one..wild ideas..even gathing crystal from the nearby rain forest and melting it ... or making a porcelain blank with a thin sheet of glass melted onto that and a thin sheet of alluminium melted on top of that☺. The porcelain approach would allow honey comb structure...fortunately I never go ahead on any of these ideas☺ ... so ok can we build such a mirror..one meter f1.8 with a curved sensor ..heck the rods forming the the strutts could be porcelain. .bake them like cakes...or single unit carbon fibre ..nil flex..what about an array of 10 inch mirrors all bought to focus in a single curved sensor in a porcelain and carbon fibre frame...something simple you can build in your garage...seven ten inch would be doable maybe...mmm but the mount..☺☺☺☺☺
