Photometry, transit observation are possible with small telescopes. This chapter details the methods by example to perform photometry, the reduction of images taken for photometric purposes and the interpretation of the results.

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

The Nature of Light,atures we see in the spectra astronomical objects. Astronomers measure the brightness of astronomical objects in terms of flux and magnitude. The use of coloured filters enables us to examine specific characteristics of the object being observed.

Imaging,, and calibrate astronomical images for use in science. We work through the operation of the telescope including pointing, focusing and camera operation. We discuss problems associated with non-stellar sources such as galaxies and nebula and planets.
