Astronomical Observations and Instrumentation

Abstract

Astronomical techniques and observing strategies are presented with a particular emphasis on currently available professional telescopes of the European Southern Observatory.

Objective

The course shall provide a basic understanding of the potential and limitation of different types of modern astronomical observations for early career researchers. The course will present technical aspects which are important to prepare, to carry out and to calibrate different types of astronomical measurements: photometry, spectroscopy, astrometry, polarimetry and others. Many practical examples will be discussed including methods for the detection of physical samples of cosmic dust. Also scientific aspects of instrumental projects and observational programs are addressed. An opportunity to contribute to solar spacecraft operations will be available during the course.
