Cím: Emission objects in a small area in Cyg OB7

Kivonat:
In an area of about ~0.3 sq.degree almost in the center of Cyg OB7 more 
than 50 new emission objects were discovered, among which 3 new HH 
objects, 2 new cometary nebulae, 2 UV Ceti type flare stars and a new 
"infrared" nebula of unknown nature. The study of the spectra of 2 
emission stars in this region shows that they are situated at a distance 
200-220 pc, which is much less than the distance of Cyg OB7.
