In 2006, the original lens for the Bausch & Lomb telescope cracked beyond repair due to constant heating and cooling from use in the heliostat. The 18-inch and 16-inch teaching telescopes on the Observing Deck were replaced by two 20-inch Planewave CDK telescopes in 2017, named Artemis and Apollo. [citation needed]
Chamberlin Observatory is an astronomical observatory owned and operated by the University of Denver.It is located in Denver, Colorado (US) in Observatory Park.It is named for Humphrey B. Chamberlin, a Denver real estate magnate who pledged $50,000 in 1888 to build and equip the facility.
It is located near the summit of Mount Blue Sky in the Arapaho National Forest approximately 60 kilometers (37 mi) west of Denver, Colorado (USA). At an elevation of 4,326 meters (14,193 ft), it is the third-highest optical/infrared observatory in the world, and was the highest until the Indian Astronomical Observatory opened in 2001.
Many modern telescopes and observatories are located in space to observe astronomical objects in wavelengths of the electromagnetic spectrum that cannot penetrate the Earth's atmosphere (such as ultraviolet radiation, X-rays, and gamma rays) and are thus impossible to observe using ground-based telescopes.

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 ...

The Meade LX200 is a family of commercial telescopes produced by Meade Instruments launched in 1992 with 8" (20.32 cm) and a 10" (25.4 cm) Schmidt–Cassegrain models on computerized altazimuth mounts. [1] [2] Two larger models, a 12" (30.48 cm) and a 16" (40.64 cm), quickly followed.
The ETX started out as a 90 mm (3-1/2") Maksutov Cassegrain telescope (first produced in 1996) and took advantage of high volume mass production and simplified optical and parts construction to open a new market for a cheap alternative to the very expensive Questar 3-1/2 Maksutov Cassegrain [1] [2] The ETX "line" has been expanded to 105 mm, and 125 mm Maksutov Cassegrains and achromatic ...
