Comet C/2025 A6 Lemmon on October 24, 2025
Comet C/2025 A6 Lemmon captured on the evening of Friday, October 24, 2025, from Monchio, Italy.
The imaging session was somewhat affected by fast moving clouds, and in the end, only 15 minutes of data were usable. However, a shorter total integration time can actually be useful with this type of target: it helps reduce motion blur caused by the comet’s movement and better preserves rapidly changing features, especially in the ion tail, which can vary significantly within just a few minutes.
Technical data
Lens: Nikon 180 mm f/2.8
Mount: ZWO AM5N
Camera: ZWO ASI 2600MC DUO
Exposures: 15×60 s at f/4
