The Fermi Gamma-ray Space Telescope, which was launched by NASA in June 2008, is a powerful space observatory which studies the high-energy gamma-ray sky Atwood (2009). Fermi’s main instrument, the Large Area Telescope (LAT), detects photons in an energy range between 20 MeV to greater than 300 GeV. The LAT is much more sensitive than its predecessor, the EGRET telescope on the Compton Gamma Ray Observatory, and is expected to find several thousand gamma-ray point sources, which is an order of magnitude more than its predecessor EGRET Hartman et al. (1999).

This is a guide for anyone interested in practical astronomy but intimidated by the idea of investing in a telescope. It explores the world of remote observing, which requires nothing more than a laptop and an Internet connection. The book aims to make readers comfortable navigating the plethora of online equipment at their disposal and to show that a challenge like imaging the Messier objects can be fun, simple, and achievable for all. In this text, all 110 Messier objects are discussed, each one remotely imaged with clear instructions on what telescope and camera combinations give the best results. Common astronomical phrases and units are all explained and illustrated to help newcomers get a grasp of terminology. Tidbits of history and quotes from Messier and other astronomers round out this beginner-friendly read, which also features a handy Quick Reference Image Library.

Le economiche webcam stanno rivoluzionando l’imaging astronomico amatoriale, fornendo un’alternativa conveniente ai CCD raffreddati, quanto meno per i soggetti più luminosi. Le webcam, che costano solo poche decine di euro, sono in grado di realizzare riprese di più alta risoluzione rispetto alle macchine fotografiche digitali grazie alla maggiore velocità di scaricamento dell’immagine che "congela" i dettagli planetari, nonostante il disturbo della turbolenta atmosfera terrestre. La loro struttura è piuttosto semplice, ed è facile rimuovere la lente frontale per utilizzarle in proiezione dell’oculare con un telescopio astronomico. Le webcam si collegano direttamente a un PC, in modo tale che si può utilizzare un apposito software per sommare sequenze di immagini, ottenendo così un notevole miglioramento qualitativo dell’immagine finale. In questo libro, Martin Mobberley introduce l’astrofilo all’uso delle webcam e all’elaborazione digitale delle immagini, mentre fornisce suggerimenti dettagliati per la ripresa del Sole, della Luna e dei pianeti. Ogni oggetto, con le specifiche tecniche di ripresa ed elaborazione, viene trattato in un capitolo a sé. Attraverso le immagini di questo libro, l’astrofilo potrà rendersi conto di quanto si possa fare applicando una webcam al proprio telescopio!

Long used in undergraduate and introductory graduate courses, "Astrophysical techniques", Seventh edition, provides an accessible yet comprehensive account of the innovate instruments, detectors, and techniques employed in astronomy and astrophysics. Emphasizing the underlying unity of all astronomical observations, this popular textbook provides a coherent state-of-the-art account of the instruments and techniques used in current astronomy and astrophysics.Fully updated throughout, this seventh edition builds upon the sixth edition, covering improved techniques and cutting-edge methods in the field, as well as other exciting new developments in gravitational waves, dark matter and energy, the use of photonics, and astronomy education and outreach, in addition to further detailed discussions on the latest scientific instruments and individual detectors.The book is written in a very accessible manner, and most of the mathematics is accessible to those who have attended a mathematics course in their final years at school. Nevertheless, the treatment of the topics in general is at a sufficiently high level to be of use to those professionals seeking technical information in areas of astronomy with which they might not be completely familiar.
