NGC6384 is a medium-scaled spiral galaxy positioned in a pentagon of Ophiuchus. The galaxy has a long axis of about 7 arc minutes, comparatively larger one included in the territory of Ophiuchus that has hardly striking galaxies. Although this image can show you the indistinct arms wound -up, telescope-aided eyes detect as only lump of elliptic light. A distance has been estimated as about 77 million light years.
