To investigate the physical properties of HII regions and some PNe about 4′ in size, a DEFPOS Fabry-Perot spectrometer has been redesigned and set up at the coudé exit of the 150 cm RTT150 telescope (f/48) at TUBITAK National Observatory (Antalya/Bakırlıtepe, Turkey). The spectrometer has a 4 ′ circular field of view and a velocity resolution of 27.27km s−1 (a spectral resolving power of 11 000) over a 200km s−1 spectral window near Hα. This work presents the details of the newly redesigned… CONTINUE READING
