Many examples of spherical t-designs have been given in [3] together with important properties of spherical designs. Web1 day ago · I can't speak to the RCs, but I've heard the nightmares regarding collimation. I do have 2 SCTs, and with spherical mirrors, you only have to adjust the secondary mirror. I doubt there is an easier scope design to collimate. I have been successfully collimating my SCTs, without any tools, other than a screwdriver and a star, for over a decade.
