The standard Schmidt-Cassegrain Telescope, or SCT, has a medium focal ratio of f/10, making it a jack-of-all-trades; good for terrestrial viewing, enjoying the planets, deep-sky observing, or astrophotography. I say "current" because the sky's atmosphere is always changing and will be different not only from night to night, but sometimes from hour to hour! We manage the entire order process through delivery and installation, troubleshooting any issues that may arise. These become very expensive to produce at large sizes due to the degree of accuracy required to manufacture the mirror. The Ritchey-Chretien is a favorite of advanced astro-imagers due to it's wide, flat field of view and it's accommodation of large sensors, The folded optical path of the RC telescope shortens the tube length for more portability, Coma and spherical aberrations are corrected on the Ritchey-Chretien for better images, The Ritchey-Chretien has a flat focal plane for sharp focus across the field, The Ritchey-Chretien has the highest cost per inch of aperture, Most RC's are large and require high-end, big equatorial mounts. Not gonna happen unless you catch someone at just the right moment needing to sell for rent money. AMOS telescopes include a 1.6 meter telescope, an 80 centimeter Beam/Director Tracker, and a 60 centimeter Laser Beam Director. While it is always true that a bigger mirror will gather more light than a smaller one, you will want to pick something that you can comfortably lift and use. RCs are great for long focal length deep sky imaging and research, but they areless ideal for visual use or planetary imaging. With outstanding features and options, Ash Domes can be found in many of the worlds most distinguished institutions. By the way, if you have a catadioptric telescope with a corrector plate at the very front of your optical tube, a dew shield or dew heater will help keep dew from forming on your optics on a damp night. RC telescopes are also very modular, field flatteners are available for expanding the corrected image circle, reducers can be integrated for faster focal ratios, and barlows can be used for longer focal lengths. Images shows the observatory with OPTIONAL bay. A Dobsonian telescope for instance, is a Newtonian reflector on a simple rotating box-style mount.
