A cropping of a wider field containing M47 and M46 (see separate uncropped image). Skyglow showing in background. No tail but Coma more evident in this image.Being near the edge of the field of the original image and having no field flattener, stars to the right in particular are elongated, and not helped with the diffraction caused by the X tape.
