Here is a photo of Comet C/2025 A6 (Lemmon) on the morning of October 16, 2025, just before sunrise. It was photographed by James Foster with my Askar 103APO (4-inch triplet refractor) at f/4 with ZWO ASI6200MC-Pro color camera. The 23 X 45 sec (17.25-minutes) exposures were stacked and then cropped and processed in Photoshop Elements and GraXpert. M94 galaxy is at the lower right of the image.  The comet will return to Earth in 1,350 years. .
This is a joint project of James Foster and Michael A. Stecker.
