Abstract Two topics of research, namely extragalactic and variable star studies represent the main attitudes of astronomical work at the Helwan Observatory. The 74 inch telescope at Kottamia (476 m, 2h.12, 29°.93 N) some 60 km to the east of Cairo is the main instrument. Some other auxiliary equipment (Cassegrain and echelle spectrographs, Westinghouse and Japanese cameras and photoelectric photometer) can be attached at both Cassegrain and Newtonian foci.
