The Moon is a useful target when the rest of the sky is bright. Its appearance changes as sunlight reaches different parts of the surface. A familiar crater can look quite different on another evening because its shadows have changed.
Look near the terminator
The terminator is the boundary between the Moon's illuminated and dark portions. Low sunlight there makes relief easier to notice. Start at low magnification and identify a broad area on a lunar map before trying to name every crater. Near full Moon, the bright surface can look flatter because much of the visible terrain has shorter shadows.
Use the Moon and planets goal in the session planner. Moonlight carries no penalty for that goal, but cloud and the Moon's height still matter. A Moon just above a roof or distant ridge may be hidden even though the calculation puts it above a level horizon.
Keep a small observing record
Choose one feature and sketch its outline, shadows and neighbouring landmarks. Mark the date, time zone, instrument and eyepiece. A telescope may reverse or invert the view; rotate your map to match before deciding that you have found the wrong feature.
If the image ripples, lower the magnification and wait for steadier moments. The cloud forecast does not measure atmospheric steadiness. Return a day or two later when possible and compare the shadow pattern. A short repeat visit can teach more than trying to identify dozens of features at once. Use normal night-time precautions, and keep optics well away from the Sun when setting up before sunset.
