Deep H α imagery of the Eridanus shells

A deep Hα image of interlocking filamentary arcs of nebulosity has been obtained with a wide-field (≈ 30o diameter) narrow-band filter camera combined with a CCD as a detector. The resultant mosaic of images, extending to a galactic latitude of 65o, has been corrected for field distortions and had galactic coordinates superimposed on it to permit accurate… CONTINUE READING
