OBJECT DESCRIPTION AND IMAGE SESSION

An nice Planetary Nebula situated close to the celestial equator, hence it is visible from both hemispheres. NGC 4361 was classified in 1987 by Chu, Jacobv and Arendt as a multiple shell PN having irregular structures in the inner structure. The nebula shows a high degree of ionization. The central star has a visual magnitude of 13,3 and shows a O type. Studies indicates that this planetary is found to be very thin in continuous radiation, that certainly suggest a low mass progenitor.

NGC 4361 has a generous size for the Newtonian 1150 focal length. Seeing was irregular during the whole session and we had 70% illuminated Moon. The night was too warm pushing the cooler to - 10 C, so all the frames were taken with - 5 C.
