<blockquote class="maintxt"><span class="maintxt">A spectrum
is worth a thousand pictures. There is a code hidden in
the light around us and it is revealed by spreading the
light into its spectrum with a spectroscope:
<p></p>
Spectroscopy was once the domain of professional
astronomers, but advances in the equipment and a
reduction in the cost are bringing it well within the
reach of amateurs.

</span>
The course assumes no previous experience or specialist
knowledge. It will put astronomical spectroscopy into
both a historic and a scientific context. It will
introduce some of the equipment and techniques used by
amateurs today, and the results that can be achieved.
<p></p>
There will be practical, hands-on demonstrations of
spectroscopy in action, with several case studies to
show how cracking the code can reveal so much about the
chemistry, temperature and motion:
<p></p>
The content of the course will provide some answers to
these questions:<br />
– What is the nature of the code hidden in starlight?<br />
– Who laid the foundations of astronomical spectroscopy?<br />
– How do spectroscopes work and how are spectra
captured?<br />
– Why is it interesting to examine the light in your
kitchen and living room?<br />
– What amateur equipment is out there today?<br />
– How is software used to process the spectrum and crack
the code?<br />
– Where can help and support be found?
<p></p>
The course aims to inspire both practicing and armchair
astronomers. It will be relaxed and interactive and
there won't be an exam at the end!<br />
