High-Precision Differential Photometry,n order to do so, the telescope–instrument uncertainties need to be evaluated and addressed, the check stars must be carefully selected, and nonstandard methods such as defocused photometry should be considered.

Radio Astronomy,chapter, we introduce some of the concepts in radio telescope design. As teaching radio telescopes are still rare, we introduce radio astronomy with three practicals. Mapping the Milky Way, detecting meteors, and observing Jupiter, the last two of which can be undertaken with low-cost radio setups.

Astrometry,s modern form, it is used to determine to the position of stars within the galaxy and the orbits of comets and asteroids, and to detect the existence of exoplanets. We show how to perform astrometry using SAO DS9 to determine the proper motion of an asteroid, and from that its distance from the Sun.
