    This is a ten pane mosaic of the Eridanus Loop region (SH2-245) taken with a QHY168C. Ha taken with an in front of lens Ha filter was combined with the OSC data to produce this image. This is a one third reduction of the original 1.5 Gb FITS image.

    The Eridanus Loop is part of the Orion-Eridanus Loop Complex. In conjunction with Barnard's Loop spans over 1200 ly across and is believed to be merging supernova remnants.
