Two comets are coming through in October that you may want to keep an eye (telescope) on. Predictions of comet brightness are always hard, and reality may be brighter or less bright than predictions. The limiting magnitude for unaided eye visibility is 6 or brighter, meaning a number of 6 or smaller.
Comet C/2025 K1 (ATLAS)
Peak magnitude of ATLAS is predicted to be 9.8 on October 8, 2025.

Comet C/2025 A6 (Lemmon)
Peak magnitude of Lemmon is predicted to be 4.3 on October 21, 2025.
