Astronomical CCD Calibrations and Observations

Astrophysical observations at optical and X-ray wavelengths are now made almost exclusively by means of charge-coupled devices (CCD). The inventors of these particularly light-sensitive sensors were honored with the Nobel Prize for physics in 2009. In this experiment, the 50 cm telescope on the roof of the physics building and a modern CCD camera are used to make some calibrated photometric measurements of an astronomical object. You will learn to operate the telescope and the CCD camera, to identify the signal and noise sources, and to calibrate scientific CCD images so far that you can determine the amount of photons detected and the quality of such measurements. The main focus is the complete calibration of the camera (bias, gain, readout, QE) and the use of professional tools, which is why the analyzes are made in the programming language PYTHON. NOTE: because of the afternoon calibration session, the usually long wait for good weather and long evenings on the telescope, and the necessary programming, the amount of work involved is much more than for a normal lab exercise!
