Note that sometimes, caching prevents you from seeing the registration link. If you do not see a link after 10:00 AM on Friday, December 13, please add a question mark plus some random characters behind the site URL.

Unless the stargazing evening is entirely in English, the registration is in Dutch, as well.

Be advised that registration requests per email will not be validated.
