Astrophotography: a didactic approach

Workshop: 11th december 2025, 19:00, Conference Hall/Library of Alovera.

The talk will be given by Drs. José Luis F. Cuñado and Pablo Molina (IMDEA nanociencia and Universidad Autónoma de Madrid).

Photographic technique has been applied to astronomy from the very begining of the invention. Nowadays digital photography greatly facilitate the acquisition of astronomical images. A wide variety of astronomical cameras are available at reasonable prices for amateur astronomers. Amateur sector not only provides visually stunning pictures, but also images of scientific interest. However, taking astronomical photographs is not an easy task. In this accessible talk, we will explain how astronomical photographs are captured, with practical, on-site demonstrations (some devices will be brought to the conference room). This will facilitate a better understanding on the subject.

The Talk

During the talk, Doctors José Luis and Pablo demonstrated various devices, explaining their operation through graphic presentations. Key aspects such as resolution, optical aberrations, digital camera sensors, atmospheric turbulence, and light pollution were addressed, as well as the use of robotic mounts for the precise tracking of the apparent movement of celestial objects in the sky. The audience was able to handle the devices on-site and gain a practical understanding of the fundamental aspects of long-exposure imaging.
