We pick the best lenses for astrophotography fans shooting a starry night sky, to suit a range of cameras and budgets
Celestron was the first large scale commercial manufacturer of the Schmidt-Cassegrain telescope, introducing its "C8" 8" diameter 2032 mm focal length, ƒ10 telescope in 1970. [7] The primary innovation Celestron/Tom Johnson devised was a method to produce Schmidt corrector plates using a vacuum to pull the glass blanks into a pre-shaped curve ...
The Swedish 1-m Solar Telescope, with a lens diameter of 43 inches, is technically the largest, with 39 inches clear for the aperture.The second largest refracting telescope in the world is the Yerkes Observatory 40 inch (102 cm) refractor, used for astronomical and scientific observation for over a century.
The NDSO mission proposes to launch a fleet of 35 space telescopes, each one a 14 m (550 in) wide spherical telescope, and each featuring an 8.5 m (330 in) diameter lens. Each of these space telescopes would be more powerful than the 6.5 m (260 in) mirror of the James Webb Space Telescope, the 2.4 m (94 in) wide mirror of the Hubble Space ...

The spherical mirror used in this telescope was extremely accurate; if scaled up to the size of the Atlantic Ocean, bumps on its surface would be about 10 cm high. [16] The Kepler photometer, mounted on NASA's Kepler space telescope (2009–2018), is the largest Schmidt camera launched into space.
This list contains proposals for space telescopes, space-based (situated in space) astronomical observatories. It is a list of past and present space observatory plans, concepts, and proposals. For observatories in orbit, see list of space telescopes. Unlike that list, this one includes concepts and proposals that are unlikely ever to be ...
There are many types of dialyte camera lenses. One popular design is perfectly symmetric, which provides good correction for many aberrations.This consists of two air-spaced achromatic doublets arranged back-to-back around a central stop, or four air spaced lens elements in total: the outer pair is biconvex and the inner pair is biconcave; one example is the Celor.
