Research-grade RCs can costs tens of thousands of dollars, if not more, for this reason." 0 review(s) .
Mount Wilson Observatory - Wikipedia Advantages of a Ritchey-Chretien Telescope: Disadvantages of a Ritchey-Chretien Telescope: The most common reflector telescope we use today was invented by Isaac Newton, which is why you'll hear this type of telescope also referred to as a Newtonian reflector.

Any laser collimator should work, but we recommend getting one that matches the size of your focuser, which is 2\" in most cases. Newtonian reflectors are the least expensive telescope design per inch of aperture, Reflectors are offered in large apertures to see into deep space, A reflector does not suffer from chromatic aberration or false color, The long open tube of a Newtonian reflector keeps dew from forming on optics, Reflectors require regular collimation for best results, Thermal air currents in a reflector's open tube assembly can distort the image, Reflectors have lower contrast than refractors of same aperture due to secondary mirror obstruction, The optics of a reflector are open to the air and so susceptible to dust & other particles, A parabolic primary mirror produces coma at edges of field, which is especially noticeable with faster f/3 -f/6 reflectors, Reflectors are not best for terrestrial use because they produce an upside-down image that cannot usually be corrected, Catadioptric telescopes have a folded optical light path for the best portability of all the designs, There is a huge selection of accessories available for Cat telescopes, allowing you to grow your system over time, Telescopes with a catadioptric design do not suffer from chromatic aberrations, Schmidt-Cassegrains and other catadioptric scopes are decently priced for the aperture and build quality, Catadioptric telescopes are available with or without an alt-azimuth or equatorial mount, Collimation of optics is required occasionally, although not as often as reflectors, Catadioptric telescopes are more complex than reflectors or refractors, with more moving parts, The secondary mirror obscures a percentage of light, similar to reflectors, Catadioptric scopes, especially larger Maksutov-Cassegrains, are more expensive than Newtonians of the same aperture, 1. We . These can work well for casual viewing and will allow you to see the planets of the solar system, other objects in the night sky, and but deep-sky objects like galaxies and nebulae may .

RadioUniversePRO is not sold separately and is supplied only with SPIDER radio telescopes. Folks who want to look at the Moon, Saturn and Jupiter occasionally but who are not interested in photography would do perfectly well with a medium-sized refractor on a simple quality alt-azimuth mount, whereas those who want to do photography would require an equatorial mount with either computerization or dual axis motor drive. If you plan to use one for viewing you will generally need to use a diagonal with your eyepiece because of the angle of the telescope when looking at the night sky. Telescopes on computerized alt-azimuth mounts, like the Celestron NexStar SE do an amazing job of finding and tracking celestial objects for visual astronomy, and a user could even take quick pictures of the Moon and bright planets, but if you want to take astro-images of objects out of our solar system, it will require an equatorial mount.
