• Astronomical twilight determination feature

Twilight is not good for watching darker celestial bodies. It is better for

watching them when the position of the Sun is in the range of the celestial

sphere below the line of altitude −18° on the transparent dial. However,

a brighter moon is not also good for watching them. Check influence of

moonlight also by using the lunar age display feature (page 25) and the

indication feature of direction and altitude of the Moon (pages 30 - 3 4).
