What to shoot tonight from where you are, with the gear you have, and a warning before a satellite crosses your frame.

Weather from Open-Meteo. Target positions from OpenNGC (CC BY-SA 4.0). Sun and Moon from low-precision formulas, good to a fraction of a degree. Streak predictions use public orbital elements: a satellite's position can be off by a few kilometres, which is a large angle for a narrow field, so treat a near-miss as a possible hit. Only publicly tracked objects are checked.
