Issued for my SCIN 109 Lab. Software that came with it offers a very elaborate view into the night sky. I would recommend the program for anyone, not just students, whom have a strong interest in astronomy. This workbook was awful!!! The questions asked gave no hint as to how to get them and no idea what the answer type was. Most of the class needed to ask 100 questions for one lab assignment. Even then the professor had to drastically curve the grades to get the average to a C. Thanks to the Canadians for making good software and not being able to teach anyone how to use it in their workbook. Boo to the makers of this workbook, you owe me some points for my GPA, or the money back for the course would be nice too.
