How recommendations work
Planning guidance, not a visibility guarantee
Position: each catalogue object is checked throughout astronomical darkness using its J2000 coordinates.
Suitability: ranking considers altitude, time above the horizon, equipment, sky brightness and Moon interference.
Conditions: cloud, haze, smoke, seeing and local obstructions can still prevent a target from being visible.
