Galileo’s Refracting Telescope Multiwavelength Astronomy

A refracting telescope (also called a refractor) is a type of optical telescope that uses a lens as its objective to form an image (also referred to a dioptric telescope). The refracting telescope design was originally used in spyglasses and astronomical telescopes but is also used for long-focus camera lenses. … See more Refractors were the earliest type of optical telescope. The first record of a refracting telescope appeared in the Netherlands about 1608, when a spectacle maker from Middelburg named Hans Lippershey unsuccessfully tried … See more Refractors suffer from residual chromatic and spherical aberration. This affects shorter focal ratios more than longer ones. A 100 mm (4 in) f/6 achromatic refractor is likely to show considerable color fringing (generally a purple halo around bright objects).

Web102 Mm REFRACTING TELESCOPE - Sep 03 2024 My first book, 'Making a Refracting Telescope', featured the making of a small refracting telescope from commonly found and inexpensive materials. The telescope had a 48mm diameter achromatic objective lens with a focal length of 450mm and was designed to be used with standard 24.5mm (0.965 inch) WebRefractor telescopes use glass lenses to bring an image into focus. Refractors are the original telescope design, and are popular with beginners and advanced users alike. High-quality refractors are prized for their high contrast, aberration-free views and images.
