The presentation by Matt Lochansky explained the steps used to do spectroscopy, basic theory, what a person could do using spectroscopy, limitations, resources, equipment, data processing, and show some of the interesting objects in our sky. Matt had many examples to help illustrate his points. The presentation was a good one and it generated a lot of questions.
Matt first presented the steps in doing spectroscopy. He also compared these steps to imaging. Many of the steps were similar. This helped orient the imaging observers and others. This was very helpful. Next he went over the basics of spectral lines and what they mean.
Another topic was what could be explored using spectroscopy. This included classifying stars, finding the star’s temperature, chemical composition, environment, velocity and motion. In addition, you can observe different types of stars, such as wolf-rayet stars, shell stars, and quasars. Matt gave examples of these stars that he observed. There are some objects that can not be observed well, such as deep sky objects.
He went over some of the equipment that he used and some good resources. It was a great presentation.
