OBJECT DESCRIPTION AND IMAGE SESSION
A massive and large galaxy located in the southern part of the constellation of Virgo near the limits of Hydra. It is one the the largest galaxies of Virgo and at least 10 times the size of our Milky Way. The image shows some companions most prominent are ESO 576-40 at 14.7 magnitude below center left; and ESO 576-31 shining at magnitude 14.5 close below to the right. It appears very elongated in a 4:1 ratio from East to West with small bright nucleolus and thin faint extensions.
The night was not really good for imaging faint objects. Lot of humidity and mist, therefore I was not able to process and combine the colors channels. The line at the right is the diffraction spike produced by gamma Hydra (2.98) located at 80 arc minutes of NGC 5084. I decided not to take it away in order to give the frame a natural appearance.
