Planetarium Christening Invitations: Time, Seats and Stars
One time, one seat count, one line of dress code. How to build a planetarium christening invitation that answers the questions before they arrive.

The planetarium dims the room at 7:30 sharp. The doors close, the projector starts, and anyone still looking for a parking space is standing in the dark. That one detail is why planetarium christening invitations have to carry more than a date: a fixed time, a real seat count and one line about what to wear.
It sounds fussy until you are the one holding the door open. Put the times and the numbers inside the invitation and the questions stop arriving on the morning you would rather spend with your family.
Planetarium christening invitations: the time comes first
A session in a dome starts when it starts, and the room has to be dark for it. Write the start time, then add "doors 20 minutes before" so nobody walks in blind. Say the same time twice in the same scene: "7:30 pm" for the people who are always early, and "half an hour before the lights go down" for the ones who are not. If the lobby opens at a different hour from the projection, give both.
- Doors at 7:00 pm and lights down at 7:30 pm, as two separate lines.
- The start time written twice, so it lands with the punctual and the late.
- The full address and the nearest parking or station on their own scene.
- One short line: "the room goes dark on time", which saves a phone call at 7:25.
Seat count: give a number, not a feeling
Forty seats in the room is a plan. "Limited capacity" is a guessing game, and every guest guesses generously. Ask the planetarium how many chairs there are, then write the number on the cover, right under the baby's name. It is the first thing people read and the thing that stops the "can I bring my cousins?" text.
Set up the RSVP so it asks how many people are coming, not just a yes or a no. A digital christening invitation can ask the one question you actually need answered. Add the date you need replies by in the same scene, and say whether the count includes children. Then you are counting heads instead of chasing messages.

A fixed time, a real number and one line about what to wear do more work than any decoration.
Deep blue, gold and a one-line dress code
Three tones are enough: deep navy for the dome, gold for the light, off-white for the text. Add a fourth and the cover starts to look like a children's party. Use a vertical photo of the dome or the night sky as the cover, because it frames itself, and keep the decorative type for the baby's name only. Everything else should read easily on a phone, since that is where it will be opened. For the dress code, "elegant, with something that catches the light" answers more questions than "formal". Put the map and the address in a separate scene: nobody wants to hunt for a street name with the car double-parked.
If the planetarium moves the session, you edit the time and the same link shows the new version. No reprints, no second round of messages. Try the design for free, see how the seat count and the address sit next to the name, and publish with one button once the details are settled. It is 29.99 EUR, paid once, and the confirmations arrive inside the invitation itself.
