Telescope X2 vs TeleCalc Usage & Stats

TeleCalc is an application that performs calculations on the optical characteristics for a telescope when its is bound with a particular ocular lens, making easier for the astronomer amateur or professional to choose an equipment. Given the equipment characteristics, calculates: - Focal length - Magnification - Minimum magnification - Maximum magnification - Exit pupil - Focal length of eyepiece - Surface brightness - Dawes resolution - Rayleight resolution - Pratical resolution - Limiting magnitude - Light gathering power - Sharpness size of FOV - Diffraction limit Developed for iOS 17 or higher.
