Pinetop and Show Low are known as the Megaplex. The Ritchey-Chretien telescope design uses two hyperbolic mirrors to correct for coma and spherical aberration. Other aberrations, such as astigmatism, can be greatly reduced with an additional field flattener. Subaru Telescope TryNormand Fullum. I have a nice spreadsheet I can send you that takes your detector parameters, star FWHM, aperture, and calculates the signal to noise ratio of a star image for a given exposure time. An OTA is simply the telescope portion of a telescope/mount/tripod package. The owner of OGS is a long-time friend.
