In 2004, Meade acquired Coronado Filters from founder and designer David Lunt, [21] [22] who produce an extensive range of specialty telescopes that allow views of the sun in Hydrogen-Alpha, and formerly, at Calcium K line wavelengths. The Meade Coronado telescopes are called "Solarmax 40" or higher depending on the model. Coronado Personal ...
When Edmund Scientific introduced the telescope in 1976 they called it "The Edmund Wide-Field Telescope" with a Part Number "2001" [5] Edmund had a public contest which ran until November 15, 1976, to come up with a name. [6] The winning name was "Astroscan 2001". The "2001" part of the name was dropped over time.
European Solar Telescope (EST), a proposed 4-meter class aperture telescope. Chinese Giant Solar Telescope (CGST), a proposed 5- to 8-meter aperture telescope. National Large Solar Telescope (NLST), is a Gregorian multi-purpose open telescope proposed to be built and installed in India and aims to study the Sun's microscopic structure.
While many fear damaging their telescope is the primary reason for avoiding sub-aperture solar filters on reflective telescopes, blinding hazards with reflectors is perhaps even more compelling. Unlike refractors, whose focal planes lie to the rear of the telescope, reflectors like SCT, Newtonian, RCT, Gregorian, and RASA telescopes have ...
The ~ 400 W of solar light from the primary is reflected by a secondary mirror fabricated from a single silicon crystal. The final f/6.6 full-disk solar image is focused on a spectrograph slit that is cooled by a flow of chilled water-propylene glycol solution. The mirrors are coated with protected silver.
