Developed specifically for SPIDER radio telescopes, the H-FEED feedhorn is designed for optimal illumination of the primary reflector, allowing for high gain while reducing side lobes and the spillover effect, thus obtaining the best possible performance from the 2.3 meter parabolic antenna. In general, the activities that many schools develop in astronomy are usually made with optical telescopes because instruments for other electromagnetic spectrum bands are considered too expensive or difficult to use. Research-grade RCs can costs tens of thousands of dollars, if not more, for this reason. Unlike Newtonians, RCsare designed to eliminate coma, which can cause stars to become misshapen near the edges of the image. The unit uses a compact 1 meter loop antenna that can be used indoors or outside. Using a moon filter is similar to wearing sunglasses to help you see better and protect your eyes from becoming overwhelmed with too much light. The lack of refractive lens elements allows this telescope design to detect wavelengths broader the visual spectrum making them very useful for measurements in the ultraviolet (UV), near-infrared (NIR), and infrared (IR) wavelengths.

After all, a telescope is often a one-time purchase, and unless we do some targeted research, we are not apt to see advertisements for telescopes like we do cars or washing machines. NexDome is the NexGeneration observatory that was designed with paying attention to problems and shortcomings of similar class observatories. 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.
