newbie question i guess. i was thinking that if your only taking out 7 or 8 mm for a parabola on a small telescope could you not use two pieces of 10 mm thick glass glued together. i am guessing if your coating it the internal reflections from the joins shouldn't be a problem. the only problem i can think of is perhaps uneven cooling of the glass. i know rather simplistic view of things but i thought i would throw it out there. the other thing is i have no idea what you would use to glue glass together with however they do glue some glass together for some camera lenses so it must be able to be done
