Abstract

The result of a survey of H-alpha emission objects in an area of approximately 25 square degrees centered on the star CD -2412765 (R.A.=16h38.m5; Dec.=-2422';1950), is presented. Only 33% of H-alpha emission stars discovered by Dolidze and Arakelyan (1959) which are located inthe present survey region, are redetected in our plates. A total number of 32 new H-alpha emission objects are found. Their position and finding charts are given.
