He made observations of Mars with an 11 cm achromatic refractor telescope made by Joseph von Fraunhofer, which was one of the first times that achromatic refractors were used for planetary observation; these were a notable improvement over the reflectors available to earlier observers.
Like William Herschel before him, he came to the correct conclusion that the visible patches on Mars were surface features rather than clouds or other transient features. Observers like Johann Hieronymus Schröter had come to the opposite conclusion.
