Catalogue of 1720 stars (1832-1834)
Karl Knorre, the First Astronomer of the Black Sea Navy carried out
visual observations in the declination range 15° to -15° and from 3h56m to 5h4m in RA
with the Ertel meridian circle.
He compiled the catalogue as the fifth sheet of the sky map for Berlin Academy of Sciences,

Using the map, Hencke discovered Astrea, the fifth minor planet in 1845,
and Hind discovered Flora, minor planet number 8 in 1847.
