Italian amateur Massimo Riccardi has developed an easy to use optical design program, loaded with powerful routines and analysis windows to design and evaluate the most advanced optical systems. It is aimed at amateurs who like to dabble in telescope design or who just like to explore the world of optics. Starting routines for the most common and favorite telescope systems makes it easy to design the basic system in minutes with just a few parameters. A powerful optimization routine can then be used to vary any number of surfaces to get the most ideal result.
