Instrumental methods for professional and amateur collaborations in planetary astronomy

Amateurcontributions to professional publications have increased exponentially over the last decades in the field of planetary astronomy. Here we review the different domains of the field in which collaborations between professional and amateur astronomersare effective and regularly lead to scientific publications.We discuss the instruments, detectors, software and methodologies typically used by amateur astronomersto collect the scientific data in the different domains of interest. Amateurcontributions to the monitoring of planets and interplanetary matter, characterization of asteroidsand comets, as well as the determination of the physical properties of Kuiper Belt Objects and exoplanetsare discussed.
