This is a 40 pane mosaic of the Orion/Taurus region. It is a continuation of my previous effort of the M45 region and the Eridanus Loop with Orion and the appropriate "filler" frames added to complete the mosaic. It shows the relationship between the Eridanus Loop and Barnard's Loop which are related.

This mosaic is a combination of OSC data and Ha taken the the QHY168C. It is quite difficult to get consistent results with color balance between this mosaic and the other two I posted.
