    This course is designed to provide participants with the basics on how to conduct their own exoplanet observations. The course will briefly cover various exoplanet detection methods, but will primarily focus on the transit method. The fundamentals of high precision photometry will be discussed in order to give the participants a good foundation for exoplanet observing. The various phases of an exoplanet observation will be covered, as well as a detailed walk-through of an actual exoplanet observation analysis using AstroImageJ. Finally, the future of exoplanet observing using small telescopes will be discussed, as well as ways in which amateur astronomers can contribute to exoplanet research.

    This course is an overview of the types of variable stars most commonly observed by AAVSO observers. We discuss the physical processes behind what makes each type variable and how this is demonstrated in their light curves. Variable star names and nomenclature are placed in a historical context to aid in understanding today’s classification scheme. You must successfully complete weekly quizzes, a journal paper review and a final examination to pass the course.

    This course will use the first half of the AAVSO Guide to CCD Photometry and will provide motivation and scientific background for doing photometry with a CCD. Topics covered include system testing and basic image calibrations from bias and dark frame subtraction to flat fielding. Students will need their own image processing software, and should have their own CCD/telescope ready to take calibration frames.

    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. Image processing software is required, but images will be provided for those without their own equipment.
