Comet C/2025 A6 Lemmon

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 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 north-west to west direction (see above image from Stellarium), about 17 degrees above the horizon. An elevated location is desirable.

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 and stack them using Sequator or Deep Sky Stacker in comet mode (keeps the comet still and creates star trails as it moves from right to left.

For now, this is an assignment, but I may schedule one or more onsite events if I find a good location. The location needs to have an unobstructed view of the western horizon, without too much light pollution. West of Worcester is good, so is VT or western NH.
