Titel: Choosing and Using Astronomical Filters Författare: Martin Griffiths Språk: Engelska Utgiven: 2015 Format: Häftad ISBN: 9781493910434Choosing and Using Astronomical Filters * Provides an in-depth look at the telescope accessories known as astronomical filters * Includes the history of different types of filters, their uses and specialist techniques * Features a basic guide to using Adobe Photoshop to further enhance images * Includes an observational guide to 100 astronomical objects that you can see better with filters, personally imaged by the author As a casual read through any of the major amateur astronomical magazines will demonstrate, there are filters available for all aspects of optical astronomy. This book provides a ready resource on the use of the following filters, among others, for observational astronomy or for imaging: * Light pollution filters * Planetary filters * Solar filters * Neutral density filters for Moon observation * Deep-sky filters, for such objects as galaxies, nebulae, and more Deep-sky objects can be imaged in much greater detail than was possible many years ago. Amateur astronomers can take photographs that rival those of professional observatories! The ability to do this has been brought about by the revolution in CCD cameras and improved filters. The book pinpoints which astronomical objects are best observed with which filters. Post-processing (using Photoshop) is also discussed, since it is helpful in further improving filtered astro images. The last part of the book is an observational guide to 100 deep sky objects that benefit from the use of filters – all personally observed by the author – with notes on the filters used (or potentially of use) in their observation and imaging. There are also notes on their celestial coordinates, magnitudes, and other pertinent information.

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.

Using High-Powered Telescopes from Home * Tells amateur astronomers how anyone at home can access and use a professional telescope at a remote observatory. * Explains the technology behind the development of remote observatories, once only used by professionals but now available to amateur observers. * Includes practical information on how to choose a remote observatory, costs, and benefits, and presents many possible projects suitable to carry out with a remote observatory. Remote Observatories for Amateur Astronomers, Authors: Hubbell, Gerald R., Williams, Richard J., Billard, Linda M. Amateur astronomers who want to enhance their capabilities to contribute to science need look no farther than this guide to using remote observatories. The contributors cover how to build your own remote observatory as well as the existing infrastructure of commercial networks of remote observatories that are available to the amateur. They provide specific advice on which programs to use based on your project objectives and offer practical project suggestions. Remotely controlled observatories have many advantages—the most obvious that the observer does not have to be physically present to carry out observations. Such an observatory can also be used more fully because its time can be scheduled and usefully shared among several astronomers working on different observing projects. More and more professional-level observatories are open to use by amateurs in this way via the Internet, and more advanced amateur astronomers can even build their own remote observatories for sharing among members of a society or interest group.

Includes some rare photos of the most iconic telescopes ever built, revealing their allure and making obvious the value of these wonderful instruments. Shows readers how to find real bargains on classic telescopes, especially using eBay and the rest of the Internet. Interviews top telescope collectors and users from both sides of the Atlantic. Includes review of some specific instruments that are often talked about on the amateur Internet forums Classic telescopes are of interest to amateur astronomers for a variety of reasons. There are the dedicated collectors, but there are also many amateurs who love the nostalgia they inspire. These telescopes "feel" different from any contemporary telescope and perhaps have a unique ability to reconnect the owner to a bygone age of craftmanship. This book takes a look at traditional telescopes built by the great instrument makers of the 18th and 19th centuries, particularly the dynastic telescope makers, including Dollond, Alvan Clark, Thomas Cooke & Sons, and Carl Zeiss. Also included are lesser luminaries such as John Brashear, John Calver, William Wray, Henry Fitz, and William Henry Mogey. 'Classic Telescopes' covers the key features of the telescopes designed by these manufacturers, and shows how a heady combination of market trends, instrument condition, and pedigree will dictate their prices at auction. 'Classic Telescopes' also shows the reader how to find real bargains! Interviews with top classic telescope collectors (and users) provide the best tips of prospecting for a genuine acquisition.

Mercury and Venus - known as the "inferior planets" because they are closer to the Sun than the Earth is - have always been regarded as difficult and even dangerous targets for amateur astronomers.Venus and Mercury, and How to Observe Them, Authors: Grego, Peter Recent advances in commercially-made instruments have, however, brought them within range of only moderately experienced observers, and certainly Mercury and Venus are by no means inferior in terms of visual delights, observing challenges...and mystery. Venus and Mercury and How to Observe Them offers a wealth of detailed practical information on every aspect of observing, from safely targeting the two planets, through visual observing, to sketching and electronic imaging. This is of course much more than a book about observing. We now know a lot more of the origin and evolution of Mercury and Venus, and Peter Grego describes the most recent theories of their probable formation, geology, and history. Not only does this include a lot about the surface of the planets, but also their internal structure, magnetic fields, and atmospheres. Peter Grego 2008, XIV, 266 p. 80 illus., 30 in color.
