Viewing And Imaging The Solar System

Viewing and Imaging the Solar System: A Guide for Amateur Astronomers is for those who want to develop their ability to observe and image Solar System objects, including the planets and moons, the Sun, and comets and asteroids. They might be beginners, or they may have already owned and used an astronomical telescope for a year or more. Newcomers are almost always wowed by sights such as the rings of Saturn and the moons of Jupiter, but have little idea how to find these objects for themselves (with the obvious exceptions of the Sun and Moon). They also need guidance about what equipment, besides a telescope, they will need. This book is written by an expert on the Solar System, who has had a lot of experience with outreach programs, which teach others how to make the most of relatively simple and low-cost equipment. That does not mean that this book is not for serious amateurs. On the contrary, it is designed to show amateur astronomers, in a relatively light-hearted—and math-free way—how to become serious.

As we speak, stunning new snapshots of our Solar System are being transmitted to Earth by a fleet of space probes, landers, and rovers. Yet nowadays, it is all too easy to take such images for granted amidst the deluge of competing visuals we scroll through every day. To truly understand the value of these incredible space photos, we first need to understand the tools that made them possible. This is the story of imaging instruments in space, detailing all the technological missteps and marvels that have allowed us to view planetary bodies like never before. From the rudimentary cameras launched in the 1950’s to the cutting-edge imaging instruments onboard the Mars Perseverance rover, this book covers more than 100 imaging systems sent aboard various spacecraft to explore near and distant planetary bodies. Featured within are some of the most striking images ever received by these pioneering instruments, including Voyager’s Pale Blue Dot, Apollo’s Blue Marble, Venera’s images from the surface of Venus, Huygens’ images of Titan, New Horizon’s images of Pluto and Arrokoth, and much more. Along the way, you will learn about advancements in data transmission, digitization, citizen science, and other fields that revolutionized space imaging, helping us peer farther and more clearly across the Solar System.

Although most people have some knowledge of the essential structure of the Solar System, few are familiar with the large and varied array of objects that travel with and between the planets in their journeys around the Sun. Imaging techniques from Earth continue to improve, while missions such as Voyager, Galileo and the Hubble Space Telescope have yielded many excellent images. Most significantly of all, several missions in recent years have shown a huge diversity of objects in close-up for the first time. The book will take advantage of the rich pool of images that is available, to tell a story of the Solar System that has not been told before. Smaller Bodies will be a collection of approximately 72 stunning images, all from the public domain but not hitherto gathered into a coherent collection, with supporting text and graphics. Each main image will be accompanied by a graphic showing the location in the Solar System of the featured object. All of these graphics will be based in a simple template providing a simple representation of the Solar System. Text will not be extensive, allowing page design to have a high priority, and will be of three kinds. ‘Main text’ (approximately 200 words) will provide stimulating introduction and some key ideas. Text headed ‘The object(s)’ (25-75 words) will provide a brief description of featured objects. Text headed ‘The image’ (25-75 words) will provide information on the source of the image and some brief technical information where required (such as in describing use of false color). The book is intended for anybody who lives in solar orbit and takes a general interest in the solar neighborhood.

Written by a well-known and experienced amateur astronomer, this is a practical primer for all aspiring observers of the planets and other Solar System objects. Whether you are a beginner or more advanced astronomer, you will find all you need in this book to help develop your knowledge and skills and move on to the next level of observing. This up-to-date, self-contained guide provides a detailed and wide-ranging background to Solar System astronomy, along with extensive practical advice and resources. Topics covered include: traditional visual observing techniques using telescopes and ancillary equipment; how to go about imaging astronomical bodies; how to conduct measurements and research of scientifically useful quality; the latest observing and imaging techniques. Whether your interests lie in observing aurorae, meteors, the Sun, the Moon, asteroids, comets, or any of the major planets, you will find all you need here to help you get started.

Now updated with the journeys of the 2012 Mars rover Curiosity and the 2020 Mars rover Perseverance, Solar System undertakes an astonishing visual journey through time and space through fascinating text, original graphics, and stunning photographs. Never before have the wonders of our solar system been so immediately accessible to readers of all ages. Award‑winning writer and broadcaster Marcus Chown combines science and history to visually and narratively explore our neighboring planets, dwarf planets, moons, asteroids, comets and more, as well as the historical figures who aided in their discoveries. From the explosive surface of the sun to the new missions on Mars; from the gargantuan rings of Saturn to the volcanoes of Io; from the latest images of Pluto from NASA's New Horizons probe, to a simulation of what the Oort Cloud might look like, Solar System offers a window seat from which to view the beauty and magnificence of space.

Deep-Sky Video Astronomy is a concise guide to using modern integrating video cameras for deep-sky viewing and imaging with the kinds of modest telescopes available commercially to amateur astronomers. It includes an introduction and a brief history of the technology, camera types, etc. The authors then examine the pros and cons of this unrefrigerated yet highly efficient technology, which is already beginning to compete with expensive astronomical cooled-chip CCD cameras in quality and ease of use. There is a thorough examination of accessories used to achieve particular results. Examples are focal reducers, Barlow lenses, and optical filters. However, the focus is mostly on the practical side of creating beautiful and detailed astronomical portraits using image-stacking software, enhancement tools like PhotoShop, and creating color images with a black-and-white camera. Practical step-by-step examples supported by tried and trusted tips show how to achieve the best possible deep-sky video portrait!

The Sun is the brightest and most accessible object in the sky, and it has much to offer the amateur astronom er with modest equipment. On most days it shows sunspots and other features that displaya wealth of fine detail and change their appearance strikingly from day to day. But observing the Sun can be dangerous. NEVER look at the Sun through a telescope or other optical aid, even for a brief instant. The Sun's intense radiation, amplified and focused by a telescope, will almost certainly cause eye injury and could weIl lead to complete blindness. Do not attempt any solar observing until you have read and understood the safety precautions and observing advice set out in Chapter 2 of this book - even if you think you have the correct equipment. Be especially wary about using filters to observe the Sun. If you have a filter that makes the Sun look dark, it is not necessarily safe, as it is largely the Sun's invisible radiation that is harmful to the eye. But provided you use the correct techniques, such as projecting the solar image onto a screen or using a specially designed, quality solar filter that fits over the telescope aperture, it is quite easy to observe the Sun safely.
