In this lecture, we will look at the distance modules and how it relates the apparent and absolute magnitudes of an object to its distance. We will also do a couple of example calculations.

The Astronomy Picture of the Day video will be uploaded each Monday.
The Misconception in Astronomy video will be uploaded each Wednesday.
The Special Topic in Astronomy video will be uploaded each Friday.

I can be reached with comments at wagnerastronomy@gmail.com. However, classes I am teaching receive priority so I will try to respond as I can to questions.

Note: Lesson 0 materials are specific for the classes that I teach. Lesson 1 will start with Chapter 1 of the textbook.
