Stargazing parties are held only at clear nights.

When it is cloudy, rainy or humid (Humidity 90% or more), we can't use telescopes.

Instructions for groups

Gunma Observatory used to accept groups of 20 or more people on weekday evenings for private use. However, as a precaution against the spread of the new coronavirus, we have stopped accepting groups to use the observatory for private parties.

For those who want to take astrophotography

If you want to manipulate a telescope by yourself or want to take astrophotography, you should apply for rental telescope, instead of attending stargazing parties.

To use rental telescopes, you have to take a license in advance. For details, please read the guidance written in Japanese → Kansoku-Taiken-Jikan ("観測体験時間").
