Comet Lemmon (C/2025 A6) over Home Lake, Lamoni Iowa. October 10, 2025.

Comet Lemmon was not particularly bright compared to other recent comets that caught the attention of the public. Here are two views of the same image. The first image above shows you the whole frame. The comet is below and to the right of the two bright, side-by-side stars that are near the center of the frame. The tail of the comet is hard to see. This image was taken with a 50mm lens on a tripod mounted Canon 5D MArk III digital camera. The ISO was cranked up to 10,000. The exposure was a 15 seconds at f5/6. Even at that the comet is not very bright. This comet was better suited to long exposure telescope images that track the comet across the sky.  Click both images to see larger versions.

This is cropped from the first image to give you a better look at the comet. The two side-by-side bright stars are to the upper left. The tail of the comet is more visible. I cropped the image to put the comet more to the left and to include the airplane crossing the sky on the right. The light on the trees on the far side of the lake is from a water plant on this side of the lake. The trees on the left block the light from hitting the trees on the right. 

In contrast, two photos of Comet NEOWISE follow. It was a much more impressive comet.
