Title

It took a while, but the mosaic is now complete. It shows Comet Lemmon C/2025 A6 on October 26, 2025, at 18:25 UT. It was taken with the Leica Apo-Telyt f-180/4.0 telephoto lens and the Asi 294. To emphasize the ion tail, only the blue images were used for the L-image. Field 1 4x5.5 minutes, field 2 5x6 minutes. The mosaic shows a field of 11x4 degrees. The color comes from parallel images taken with the Zeiss Milvus f-135/2.8 and the Nikon Z6astromod, each 7 minutes per field. Michael Jäger, Gerald Rhemann
