Stargazing in Berlin: Which Observatory Night Shows You the Most Sky
Every public telescope night at the Archenhold and Wilhelm-Foerster observatories this autumn, with the Berlin sky computed for each session. Pick a night and a start time to see where Saturn and the Moon stand, how bright the Moon is, and which observatory is open.
Programme of the Stiftung Planetarium Berlin as published on 27 September 2026; sky positions computed for central Berlin.
Berlin has two public observatories that open their big telescopes to anyone with a €12 ticket, and the night you pick decides what you see. A full Moon washes out the galaxies, Saturn sits low behind the trees at 20:00 in early October, and after the clocks go back the 20:00 session is finally dark. Pick a Thursday, Friday or Saturday and a start time, and the board shows the sky over Berlin at that hour and which observatory has its telescope open.
What the sky board shows
Every public telescope night at the two big observatories in Berlin from 1 October to 26 December 2026: the Archenhold Observatory in Treptower Park, open Thursday to Saturday, and the Wilhelm-Foerster Observatory on the Insulaner in Schöneberg, open Friday and Saturday. Each night in the calendar shows the Moon phase, whether a bright Moon is up at the session hour, and which observatory has its telescope open. Pick a night and a start time, 18:00 for the children’s sessions or 20:00 and 22:00 for adults, and the chart shows the sky over Berlin at that moment.
Where the numbers come from
Session dates and times come from the published programme of the Stiftung Planetarium Berlin, read on 27 September 2026. Tickets cost €12, or €8 reduced, for a 90-minute session.
Positions of the Moon, Saturn, Jupiter and the brightest stars are computed for central Berlin with standard low-precision formulas, accurate to about a degree, which is plenty to tell whether something clears the rooftops.
The clock change on 25 October is built in, so 20:00 in November really is 20:00 local time.
How to read the answer
A dark calendar cell means the Moon is down or barely lit at that hour, which is best for star clusters and galaxies. A pale cell means a bright Moon is up: the Moon itself is then the best target. Saturn is at opposition on 4 October, so in October the 22:00 session sees it higher, and from November the 20:00 session is the better one. The telescope sessions are hosted in German, and clouds move the programme indoors, so check the forecast on the morning you go.
