In continuation of some researches previously reported on the structure of clusters of nebulae we here discuss some of the data obtained with the 18-inch Schmidt telescope on Palomar Mountain concerning the Pegasus cluster of nebulae (R.A. 23h 17m; Decl. + 7° 50', 1930; gal. long. 55°, lat. -49°). According to Hubble and Humason [1] this cluster consists of about 100 nebulae scattered over an area roughly 10 in diameter. The Pegasus cluster lies at a distance of about 7.25 million parsecs and is centered around the two brightest objects NGC 7619 and 7626 which are slightly fainter than the photographic apparent magnitude 13. The most frequent apparent magnitude in the cluster is about 15.5.
