Danish people call it 'Lyse nætter', literally meaning 'bright nights'. This natural phenomenon occurs when the sun does not set lower than 18 degrees under the horizon. Under this zone, the light from the sun does not officially have an influence (unless another light phenomenon occurs, like zodiacal lights...) on the brightness of the sky, this is what we call astronomical night. When the sun is located between 0 and 18 degrees below the horizon, its light is more or less visible to the viewer, and it affects tremendously how we see the sky. This 'twilight' (after sunset) or 'dawn' (before sunrise) zone is divided into three sub-zones depending on the position of the sun: The civil twilight (very bright), the nautical twilight (dimmer), and the astronomical twilight (very dark).
At a latitude of 56-57 degrees North like Denmark, the sun never goes down below the astronomical twilight/dawn during late spring and summer days (Late April till early August), making the nights brighter and brighter towards the summer solstice. May is a month of transition in the southern Scandinavian country, but also a month of opportunity and hope. It's the month where a lot of sky phenomena can occur at the same time, making an astrophotographer's life very interesting!
While May is not the best month of the year for deep-sky observation, you should definitely consider shooting wide angle and medium format astrophotography. Our galaxy, the Milky Way is still visible, along with the rest of the night sky. The southern portion of the night sky is way darker, enabling you to still get decent shots around midnight/1am, but you can also take awesome landscapes of the twilight.
Even though noctilucent clouds merely appear when the Earth is at its farthest away from the sun (June, July), some sightings are still possible by the end of May and during the bright nights, as the mesosphere gets colder. One more reason to spend the late hours of the mild nights in Denmark!
