jak obiecałem nadużyłem programu MODAS - oto co wygenerował(na automacie dla warunków które określiłes wcześniej odnośnie światłosiły układu i lg nie uwzględniona obstrukcja:
dall-kirkham
cassegrain "klasyczny"
RC
i newton f/4 dla porównania
można pewnie zoptymalizować to trochę ale to zajęcie na długie zimowe wieczory i wielkich nadziei nie rokujące
detale wymiarowe dla cassegraina:

ps. co do możliwości wykonawczych tego z cienkich płyt to już nie odważę się mędrkować na ten temat
pps. zachęcam do pobawienia się tym programem wersja demo jest za darmochę grzech nie skorzystać->
