While there are some exceptions to the rule, achromatic refractors use two lenses in their design, and while they are economical, achromats are only capable of focusing two out of three wavelengths of light. An alt-azimuth mount is designed to move north, south, east or west, either manually or electronically via a hand controller. The mount you choose also dictates the total weight and heft of the telescope system. In general, the "best" telescope mount is a solidly built equatorial mount and tripod that has a large enough weight capacity to easily carry the telescope and any other accessories you plan to use. Most large Ritchey-Chretien telescopes have an open truss tube design rather than a closed tube to decrease the weight of the optical tube as a whole. The2.2 meterinside diameter provides plenty of space to operate up to a 14 Schmidt Cass or a refractor 1400mm long.

With the impasse at Mauna Kea soon to enter its third month, and with the 2020 Legislature convening in January, Civil Beat reached out to all 76 state legislators to see where they stand on the. An APO telescope, or apochromatic refractor, uses 3 lenses to bring all three wavelengths of light to a single focus to produce an image virtually free of extraneous color. 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. There are also focal reducers available to shorten a longer focal length and create a wider field that is better for astro-imaging, especially with today's larger sensors. My club's .6m RC cost almost 300K 20 years ago and the dome and building it's housed in was almost 100K. Smaller aperture RC telescopes are available for amateur astronomers who wish to work with an instrument that was designed for astro-imaging, including this inexpensive entry-level Ritchey-Chretien, the Apertura 6" f/9 Ritchey-Chretien OTA telescope.
