This book is for the aging amateur astronomy population, including newcomers to astronomy in their retirement and hobbyists who loved peering through a telescope as a child.Astronomy for Older Eyes Author: James L. Chen, Adam (ILT) Chen, James L. Chen Whether a novice or an experienced observer, the practice of astronomy differs over the years. This guide will extend the enjoyment of astronomy well into the Golden Years by addressing topics such as eye and overall health issues, recommendations on telescope equipment, and astronomy-related social activities especially suited for seniors. Many Baby-Boomers reaching retirement age are seeking new activities, and amateur astronomy is a perfect fit as a leisure time activity. Established backyard astronomers who began their love of astronomy in their youth, meanwhile, may face many physical and mental challenges in continuing their lifelong hobby as they age beyond their 55th birthdays. That perfect telescope purchased when they were thirty years old now suddenly at sixty years old feels like an immovable object in the living room. The 20/20 eyesight has given way to reading glasses or bifocals. Treasured eyepieces feel all wrong. Growing old is a natural process of life, but astronomy is timeless.With a little knowledge and some lifestyle adjustments, older astronomers can still enjoy backyard observing well into their seventies, eighties and even into their nineties.

This book tells the story of two giants and a dwarf. The giants, Uranus and Neptune, are mostly huge balls of gas, and they make their home in the remotest reaches of the Solar System. The dwarf, Pluto, which can usually be found even farther out than the two giants, was always small, but up until a short while ago, it enjoyed the same status as the other planets, a full-fledged member of the Solar System. Today, Pluto has been re-classified as a "dwarf planet."Uranus, Neptune, and Pluto and How to Observe Them, Authors: Schmude, Jr., Richard In this clear and succinct overview of the current research on these remote Solar System objects, Richard Schmude, Jr., tells us what facts we do know about these faraway entities, what we are seeking to know, and also how to observe them for yourself, using commercially available telescopes. He also explains why Pluto was re-classified and what it means, exactly, to be a dwarf planet. Intrigued by these objects since boyhood, Schmude has compiled a loving tribute to them, if not making them warm and fuzzy, at least making them seem less remote and bringing them into our current frame of reference, giving them personality and revealing their worth in our understanding of the structure and nature of the Solar System in which we live.

Guides observers to the best nebulous objects in the night sky from any latitude, including the incorporation of numerous Southern Hemisphere objects Authored by a recipient of the "Master Observer Award" of the Astronomical League, who is extremely familiar with the instrumentation needed to view and image nebulae as well as having a deep understanding of their properties Contains many stunning pictures illustrating the beautiful and multi-colored nebulae of the Milky Way Observing Nebulae This book enables anyone with suitable instruments to undertake an examination of nebulae and see or photograph them in detail. Nebulae, ethereal clouds of gas and dust, are among the most beautiful objects to view in the night sky. These star-forming regions are a common target for observers and photographers. Griffiths describes many of the brightest and best nebulae and includes some challenges for the more experienced observer. Readers learn the many interesting astrophysical properties of these clouds, which are an important subject of study in astronomy and astrobiology. Non-mathematical in approach, the text is easily accessible to anyone with an interest in the subject. A special feature is the inclusion of an observational guide to 70 objects personally observed or imaged by the author. The guide also includes photographs of each object for ease of identification along with their celestial coordinates, magnitudes and other pertinent information. Observing Nebulae provides a ready resource to allow anyone with a little experience in astronomy, whether professional or amateur, to locate, identify and record the nebulae in our home galaxy. The author enables the observer to use a telescope and filters to the best advantage to see these celestial wonders, or to couple filters to a CCD camera or digital SLR camera in order to take quality images of celestial objects. By using these techniques it is even possible to make a valid contribution to professional investigations. And the views are unbeatable.

The uniquely beautiful light display of an aurora is the result of charged particles colliding with tenuous atmospheric oxygen and nitrogen, more than 60 miles above the Earth, when the magnetosphere is disturbed by changes in the solar wind.Aurora - Observing and Recording Nature's Spectacular Light Show, Authors: Bone, Neil Often - and incorrectly - regarded as being confined to high northern and southern latitudes, major auroral displays are visible from even the southern USA and the south of England, and occur perhaps twenty times in each eleven-year sunspot cycle. Major auroral storms always cause great interest and excitement in the media, and of course provide practical astronomers with the opportunity to study and image them. This book describes the aurora from the amateur observational viewpoint, discusses professional studies of auroral and geomagnetic phenomena to put amateur work in context, and explains how practical observers can go about observing and recording auroral displays.

Provides a one-stop shop for the amateur variable star observer. Features chapters on binocular variable stars and photometric study of variable stars, topics that have not been addressed in most other amateur astronomy books. Uses non-mathematical language that is easily accessible to anyone with a general interest in astronomy. Provides basic and advanced information for an activity many amateur astronomers pursue once they have developed some skills in deep sky observing This book contains everything you need to know about variable stars -- stars whose brightness varies noticeably over time. The study of variable stars has been a particularly popular area of research for amateurs for many years; the material contained herein serves as both an introduction to amateur astronomers and a useful reference source for seasoned variable star observers.  With its thorough, non-mathematical descriptions of variable stars and tips for how to see them, this book enables novices and experts alike to set off into the field and observe a wide range of delightful sights. It strikes a balance between easily visible objects that can be seen in any telescope or binoculars, and variable stars that are a direct challenge to those with large aperture equipment or access to photometric tools and methods. After helping the observer differentiate between variable star types, the author goes on to explain the skills needed to operate a telescope and other equipment, as well as how to couple filters to a CCD camera or digital SLR camera in order to photometrically record these celestial objects. Further, the book includes an observational guide to 50 objects for study, with finder charts and data about light curves for ease of identification, along with the stars’ celestial coordinates, magnitudes, and other pertinent information.

En introduktion till solens historia.Solar History - An Introduction - Författare: Claudio Vita-Finzi Beyond the four centuries of sunspot observation and the five decades during which artificial satellites have monitored the Sun – that is to say for 99.99999% of the Sun's existence – our knowledge of solar history depends largely on analogy with kindred main sequence stars, on the outcome of various kinds of modelling, and on indirect measures of solar activity. They include the analysis of lunar rocks and meteorites for evidence of solar flares and other components of the solar cosmic-ray (SCR) flux, and the measurement of cosmogenic isotopes in wood, stratified ice and marine sediments to evaluate changes in the galactic cosmic-ray (GCR) flux and thus infer changes in the sheltering magnetic fields of the solar wind. In addition, shifts in the global atmospheric circulation which appear to result from cyclic fluctuations in solar irradiance have left their mark in river sediments and in the isotopic composition of cave deposits. In this volume the results these sources have already produced have been summarised, paying special attention to those that reflect processes in different parts of the Sun's interior and that display periodicities and trends which may enable us to forecast future large-scale environmental changes.

* Titel: Visually Observing Comets * Författare: David A. J. Seargent * Språk: Engelska * Utgiven: 2017 * Format: Häftad * ISBN: 9781316639931 * Includes suggestions for observing periodic comets in addition to finding new comets * Small trim size and to-the-point text make this ideal for use as an on-the-go-reference * Explains the possibilities for an amateur observer to make a significant contribution to planetary science through comet-spotting In these days of computers and CCD cameras, visual comet observers can still contribute scientifically useful data with the help of this handy reference for use in the field. Comets are one of the principal areas for productive pro-amateur collaboration in astronomy, but finding comets requires a different approach than the observing of more predictable targets. Principally directed toward amateur astronomers who prefer visual observing or who are interested in discovering a new comet or visually monitoring the behavior of known comets, it includes all the advice needed to thrive as a comet observer. After presenting a brief overview of the nature of comets and how we came to the modern understanding of comets, this book details the various types of observations that can usefully be carried out at the eyepiece of a telescope. Subjects range from how to search for new comets to visually estimating the brightness of comets and the length and orientation of tails, in addition to what to look for in comet heads and tails. Details are also given of 20 periodic comets, predicted to return between the years 2017 and 2027, that are expected to become suitable targets for visual observing, in addition to information on a famous comet potentially visible each year and subject to great outbursts of brightness.

Visualizes relevant physical information of stars and extended objects in an attractive and comprehensive way with different colors, symbol types, and sizes Covers the entire sky, both the Northern and Southern Hemisphere Contains position (and physical) information on enough stars to support star-hopping The Constellation Observing Atlas Designed for anyone who wishes to learn the constellations or observe the best and brightest deep sky objects and double stars, this book contains an alphabetical list of constellations complete with star maps, historical background, and highlights of deep sky objects. Each entry contains position and physical information on enough stars to support astronomers in star-hopping, swinging the telescope from star to star to star to arrive at a faint target. It provides a carefully selected list of accessible and rewarding deep sky objects. Full-color maps show the constellations, with star types (spectral and physical) indicated by the colors used on the map. Extended objects such as galaxies and nebulae are shown with the approximate apparent size in the sky. With unmatched thoroughness and accessibility, this is a constellation atlas that makes the ideal companion to a night's telescope viewing, for novices and expert amateur astronomers alike. Easy to navigate and refer to, it is the key that unlocks the door to greater night sky exploration.

This book is a unique work satisfying the need for a modern, comprehensive review of all major aspects of galaxy observation.Galaxies and How to Observe Them, Authors: Steinicke, Wolfgang, Jakiel, Richard The book combines the physical background on the nature and data of galaxies, the relevant instrumentation and viewing techniques, and finally the targets and their individual appearance in telescopes of various apertures. A comprehensive sample of galaxies, including quasars, groups and clusters of galaxies is presented. This combination of theoretical knowledge and practical information guarantees successful observing sessions. Furthermore, the book is clearly structured with outstanding images and graphics.

Nebulae are the places where the stars are born. For amateur astronomers, the many different kinds of nebulae vary from "easy" targets that can be seen with modest equipment under mediocre skies, to more obscure "challenging" objects that require experienced observers, more powerful telescopes and excellent observation conditions.Nebulae and How to Observe Them, Authors: Coe, Steven The concept of this book - and of the series - is to present an up-to-date detailed description and categorisation of nebulae, and then to instruct the reader in the best ways to successfully observe and record the large range of astronomical objects that fall under the general heading of "nebulae". Nebulae and How to Observe Them is a comprehensive mine of information for all levels of amateur observers, from the beginner to the experienced. The Astronomers Observing Guides are designed for practical amateur astronomers who not only want to observe, but want to know the details of exactly what they are looking at ASTRONOMERS OBSERVING GUIDES provide up-to-date information for amateur astronomers who want to know all about what it is they are observing. This is the basis of the first part of the book. The second part details observing techniques for practical astronomers, working with a range of different instruments.
