    This course will use the second half of the AAVSO Guide to CCD Photometry and will cover topics including optimal image photometry settings and techniques, transformation, and basic error estimation. We'll also discuss how to plan an observing run to optimize the scientific return of your observations. Part I of this course is not a prerequisite, but is very strongly encouraged for new CCD photometrists. Students will need their own image processing software, and should have their own CCD/telescope ready to take science frames.

    This course will utilize the updated DSLR photometry manual as its guide. This manual is a basic introduction and guide to using a DSLR camera to make variable star observations. The target audience is first-time beginner to intermediate level DSLR observers, although advanced observers may find the content useful as well.
