Historical Jan Fric's plates at the Ondrejov Observatory

Coauthors: Rene Hudec

There are 45 historical plates taken by small aperture cameras in the years 1895/96 by Jan Fric (brother of the founder of the Ondrejov Observatory) in Prague and located in the archive of the Ondrejov Observatory. We will present details on these plates. Most of the plates were taken with the goal to improve the photographic process used at that time for astronomical imaging. The limiting magnitude is mag 13 in the best cases. These efforts were interrupted in January 1897 by the dead of Jan Fric at an age of only 34 years.
