ANALYTICAL LUNAR INSTRUMENTATION
Precision Astronomical Lunar Observation
Precision scientific lunar observatory calculating true moon phases, topocentric altitude, azimuth, rise & set events, observation windows, and local observing journal.
Calculated Ephemerides
ELP2000 / VSOP87True topocentric coordinates accounting for atmospheric refraction, lunar distance variation, and observer elevation.
24-Hour Horizon Planner
SKY BRIGHTNESSAnalyze moon visibility across astronomical night, nautical twilight, civil twilight, and full daylight for optimal contrast.
Private Local Logbook
INDEXEDDBZero tracking and zero cloud dependencies. Store your visual observations, equipment notes, and local conditions safely.
Observer Protocol Note: All calculations run locally in the browser utilizing Astronomy Engine. Visual observations depend on local atmospheric conditions and terrain obstacles.
