Comet C/2025 A6 Lemmon & Crescent moonset

Comet C/2025 A6 (Lemmon) is a non-periodic comet approaching our solar system and making its closest approach to Earth on October 21, when it will be most visible. The moon gets in the way after the 25th and the comet wont come far enough over the horizon until the 19th.
If weather doesn't cooperate for this day, I may move the event to an earlier day.

The magnitude of the comet will only be a 10, but it may be nicely visible if we have clear skies. The comet will be in the west, about 20 degrees above the horizon, and it sets around 9pm at 298 degrees azimuth (west-north-west).

If you come a bit earlier (as I plan to), you can record a 10% crescent moon setting at 7:05pm and azimuth of 232 degrees (south west).

Use the longest lens you got for this, the comet will be small and faint. Take as many photos as you can with the comet centered. Settings: follow the rule of 600: 600 divided by your focal length. If you use a 600mm lens, your exposure time would be 1 second. Open aperture as wide as you can (likely 5.6-6.7) and adjust ISO accordingly (likely 12800).

In post processing, stack the photos using Sequator or Deep Sky Stacker in comet mode (keeps the comet still and creates star trails as it moves from right to left).
