Planning your stay

New moon phases

The best time for astronomy are the days around the new moon, because then no disturbing moonlight hinders the perception of faint objects in the sky. In the table opposite, we have therefore listed the time slots for an optimal astro vacation for the astro season 2025 and 2026. They start 1 week before and end 1 week after the new moon.

Please note that our guest operation is seasonal. You can book in during the months of April to September, which are ideal for astronomy. Our operation is closed during the months of October to March.

Book your return flight as close as possible to the dates specified in the time window for the month in question.

Is there still an apartment available?

The tables show whether an apartment is still available in the new moon phase of the current year and the coming years that you want. It is generally advisable to book early.
