摘要：
In this paper we present the Halpha map, the 2D velocity field, and the rotation curve of the galaxy NGC 784 obtained with the ByuFOSC2 scanning Fabry-Perot interferometer, attached at the prime focus of the 2.6-m telescope of Byurakan Observatory. The H-alpha image shows several HII condensations along the major axis of the galaxy. The galaxy has an asymmetric distribution of the a H-alpha emission. The rotation curve is quite symmetric with a low gradient in the central part of the galaxy.
