A Detailed Insight Into the 8-Inch and 6-Inch Telescopes Like binoculars and the corrective lens, telescopes let us see things using our eyes. For practical usage of telescopes, it is always advisable to keep away any corrective lens before viewing through the telescopes. There are many different telescopes, each designed for a specific purpose. For…
The primary mirror is a part of a reflecting telescope that collects and focuses light from distant objects. Knowing the design and material of a mirror is fundamental to understanding a telescope’s abilities, as the primary mirror is responsible for capturing and manipulating light to form images of distant celestial objects. The primary mirror’s primary…
How Galileo’s Telescope Created the Modern Science of Astronomy Galileo challenged conventional views of the universeby observing by observing objects in the sky then applying the laws of mathematics and logic to what he saw. He turned the telescope into an important tool of understanding the universe we live in. Before Galileo turned his telescope…
There are different types of telescopes available on the market depending on different features. Here we will discuss the tube assembly and light path of five types of telescopes. Fig 1: tube assembly and light path of five types of telescopes The image shows how they are different in assembly and lightpaths and they have…
William Parsons, also known as the 3rd Earl of Rosse, was an English astronomer, naturalist, and engineer who made significant contributions to the field of astronomy through his telescope discoveries. Parsons built his own telescope, the “Leviathan of Parsonstown,” which was the largest known telescope of its time with an aperture of 1.8m. Using this…
A refractor telescope is a type of optical telescope that uses a refracting lens. Refractors are made of glass or plastic, to gather and focus light from distant objects. The light is bent as it passes through the lens, forming an image at a specific point, which is then magnified by the eyepiece. Refractor telescopes…
Brass Telescopes You might have seen an old-fashioned telescope-type object used by navigators or the captain of a large wooden ship in documentaries on the 17th or 18th-century events. This is possibly the Brass telescope we are going to discuss now. This is the kind of thing you get by inheritance. It symbolizes legacy and…
James Gregory was a Scottish mathematician and astronomer, born in November 1638 in Drumoak, near Aberdeen, Scotland. He is best known for his description of the first practical reflecting telescope, now known as the Gregorian telescope. James Gregory made important mathematical discoveries, including infinite series representations for various trigonometric functions. Despite his significant contributions to…
Astronomy Project For Kids: How to Make Constellation Cups We sometimes think that astronomy is a field only for the elders. But we already know about many astronomers and star gazers, who started their journey in astronomy at an early age of life. Here we will describe an amazing astronomy project that you can do…
To make a Dobsonian telescope, start by researching designs and choosing a mirror size based on your budget and light gathering needs. Sketch a design, prepare a materials list, and cut plywood or MDF pieces for the mirror and rocker boxes. Assemble the boxes, ensuring the mirror box is light-tight, and build a mirror cell…
The Advantages of a Rich Field Telescope (RFT) A Rich Field telescope is a somewhat perplexing term. Therefore, what does this imply?What is a Telescope with a Large Field of View? They are low-magnification telescopes with a wide field of view. These binoculars provide se benefits, including viewing large sky areas.There are methods for studying…
The finderscope is a part of a telescope that helps locate and center celestial objects in the primary telescope. Knowing the design and function of a finderscope allows astronomers to accurately and efficiently locate celestial objects. The finderscope is a secondary telescope mounted atop the Optical Tube Assembly (OTA), designed specifically to help astronomers locate…
Resolving power of a telescope refers to the ability of a telescope to detect the small details. This article will explain this term so that you can grasp it easily and provide a lot of photographs and drawings. Firstly, let’s look at a double star. What is resolving power? It is the ability of a…
Refracting and reflecting telescopes differ in their method of collecting and focusing light to form an image. Refracting telescopes, or refractors, use a lens, while reflecting telescopes, or reflectors, use a mirror. The image formation process differs, with refractors using the lens’s refractive power and reflectors using the mirror’s curvature. Chromatic aberration is a problem…
Christiaan Huygens was a Dutch mathematician, astronomer, and physicist who made significant contributions to the field of telescope design. He invented the Huygenian eyepiece, a type of compound eyepiece that reduced image distortion, and built refracting telescopes with improved optics and a focal length of 67 meters. Huygens’ telescope designs and innovations allowed for better…
Astronomy as a Hobby – Guide There’s something inspiring and awesome about stargazing that makes you reflect on our lives as humans on Earth. Simply viewing starts at night can deepen your sense of awareness, but having the right tools can also be helpful to increase your knowledge and wonder about the solar system. That…
A telescope is an optical instrument designed to observe distant celestial objects. Telescopes have types, each with specific setup requirements and basic operational principles. Eyepieces are crucial components of telescopes, allowing for magnification and focus adjustments. Use a telescope by following a step-by-step guide tailored for beginners. Setting up a telescope requires preparation and attention…

Sir Isaac Newton invented the reflecting telescope in 1668, a significant contribution to the field of optics that impacted the development of telescopes during the scientific revolution. His main innovation was the use of a concave mirror to gather light, which helped combat chromatic aberration and revolutionized telescope technology. Newton’s reflecting telescope design, known as…
Johannes Kepler was a German astronomer, mathematician, and natural philosopher known for his work in astronomy, optics, and the invention of the Keplerian telescope.
