A Cooke telescope in Poland

 In Warsaw in 1898 an observatory was established a short distance north west of the university. The observatory had originally belonged to the Polish amateur astronomer Jan Walery Jedrzejewicz (1835-1887) at Plonsk in central Poland.

Among the equipment in the observatory was a 5 inch Thomas Cooke & Sons telescope. Among the objects that Jedrzejewicz observed were double stars, sunspots, lunar occultations and the positions of 16 comets.
