Reflecting telescope design pdf download

Laurent Cassegrain (ca. 1629 – September 1, 1693) was a Catholic priest who is notable as the probable inventor of the Cassegrain reflector, a folded two-mirror reflecting telescope design.

This particular design is also unusual in that it is a Cassegrain design but has a refractor style rack and pinion focuser. Newton's first reflecting telescope was completed in 1668 and is the earliest known functional reflecting telescope. The Newtonian telescope's simple design makes it very popular with amateur telescope makers. Since reflecting telescopes use mirrors, the design is sometimes referred to as a "catoptric" telescope. James Gregory was a contemporary of Isaac Newton, both often worked simultaneously on similar projects. Gregory's design was published in 1663 and pre-dates the first practical reflecting telescope, the Newtonian telescope, built by Sir… Newton's telescope managed to highly impress the Royal Society's council members, resulting in Newton's election as an official member of the Society. In 1672, a Frenchman named Cassegrain (no records of first name present) constructed a…

When approaching the design of this second telescope various issues were addressed. The idea of an oval (elliptical) reflector arose as a response to the design problems of constructing a very large reflector. With a diameter of 17 meters for the reflecting surface, it was the largest in the world before the construction of H.E.S.S. II. This has significant advantages for spectrographs and other heavy instruments typically used at research observatories. Most modern research telescopes can be configured into a Nasmyth telescope (i.e. to use the "Nasmyth Focus"). As of November 2017[update], five mirrors had been cast and the construction of the summit facility has begun.

Electronics comes into the design and building of stepper motor drives. By the time you have built a few scopes you will have increased your knowledge in optics, engineering and electronics. The best thing about telescope making today is that the internet has an almost limitless supply of information in all aspects of telescope making. Go for it!

Main Principle. Advances in Modern Telescope Design (1) telescoPes: maKe your oWn refractor There are many different types of telescopes but the two most basic and common types are reflector and refractor telescopes. Reflectors use mirrors, whereas refractors use lenses to gather light and magnify objects. Follow this guide to make your own refractor. Dobsonian telescopes are popular with amateur telescope makers for their ease of design and construction, portability, and their use of large optical mirrors. Pioneered by John Dobson in the 1960s, the instrument combines a Newtonian reflector telescope with a unique two-axis movable base. A Standard Folded design would put the 6 inch f/15 into a tube 12 inches in diameter and 29 inches long – short and squat. The Offset Folded Refractor is contained in a tube 10 inches in diameter and 36 inches long; still pretty short and squat but slightly thinner and a bit more compact. The following diagram illustrate the differences. Above: Optical layout of a typical Cassegrain reflecting telescope This section details the optical design and inherent aberrations of Cassegrain-type reflecting telescopes. For a more basic overview of these designs please see the Ritchey-Chrétien page and the Cassegrain page. For a review of the optical design terms, see the Optical Aberrationsand Optical Design sections. Star Testing Your Telescope the magnitude of the defect. Severe errors on any telescope include astigmatism that origi-nates on the glass, bad zones or severe roughness. These warrant returning the telescope. If the errors are minor, weigh the likelihood that you will get better optics at the same price. Also consider what you bought

Two main types: refractive and reflective. ✓ As we are For research telescopes or for astrophotography, we will place the analyzer Design of the telescope. A refracting telescope uses a large diameter objective lens with a long focal length to There are many designs of reflecting telescopes, mostly with a primary  Primary mirror (for reflecting telescopes), which carries the same role as the primary lens in a telescope (Newtonian design) are shown in Figure 2.
