One of the fastest telescopes of the world!The UWF300_1 package combines the highly-corrected 300mm f1.3 UWF OTA with our outstanding DDM100 mount. This groundbreaking optical design is ideal for short exposure, high SNR wide field surveys.
UWF300 Optical LayoutThe UWF300 uses a prime focus configuration. The main mirror is a high order asphere and in the prime focus we use a 5 Lens corrector to correct any field aberrations in a wavelength range from 400nm to 700nm. With the ultra short focal length and wide field it is the ideal telescope for fast sky surveys searching for brighter objects. The resolution with modern small pixel CMOS is nevertheless surprisingly high even with such a short focal length. It can also be arranged in arrays on our DDM mounts.
