Beschreibung
Transmission grating spectroscopes look like simple filters and are designed to screw into place on the eyepiece tube of a telescope for visual use, or into a camera adapter for digicam or CCD imaging. They are relatively inexpensive and by far the easiest type of astronomical spectroscope to use, and so are the starting point for most beginners.
Using the most popular commercially made filter gratings - from Rainbow Optics in the United States to Star Analyser in the United Kingdon - as examples, the book provides all the information needed to set up and use the grating to obtain stellar spectra. It also presents methods of analyzing the results. No heavy mathematics or formulas are involved, although a reasonable level of proficiency in using an astronomic telescope and, if relevant, imaging camera, is assumed.
This book contains many practical hints and tips - something that is almost essential to success when starting out. It encourages new users to get quick results, and by following the worked examples, successfully carry out basic analysis of spectra.
With this author's earlier (intermediate level) book, Astronomical Spectroscopy for Amateurs, this book provides a perfect companion for those who want to know a lot more about what spectrographs tell us about the stars. And you'd be surprised at how much they tell us!
Grating Spectroscopes and How to Use Them is written for amateur astronomers who are just getting into this field of astronomy. Transmission grating spectroscopes look like simple filters and are designed to screw into place on the eyepiece of a telescope for visual use, or into the camera adapter for digicam or CCD imaging. Using the most popular commercially made filter gratings – Rainbow Optics (US) and Star Analyzer (UK) – as examples, this book provides the reader with information on how to set up and use the grating one needs to obtain stellar spectrograms. It also discusses several methods on analyzing the results. This book is written in an easy to read style, perfect for getting started on the first night using the spectroscope, and specifically showing how the simple transmission filter is used on the camera or telescope. No heavy mathematics or formulas are involved, and there are many practical hints and tips – something that is almost essential to success when starting out. This book helps readers to achieve quick results, and by following the worked examples, they can successfully carry out basic analysis of the spectra.
The perfect starting point for first-time spectroscope users, with no heavy mathematics and with information on how to buy and use an entry-level spectroscope, which costs $150 vs. the $1,500+ of more advanced types Describes how to buy and use an entry-level spectroscope Includes specific details on the transmission filters for cameras and telescopes Packed with practical tips on how to use simple commercial grating spectroscopes Presents clear worked-through examples of how to analyze spectra from the stars and planets Includes supplementary material: sn.pub/extras
