Every Stellara ships with 13 interchangeable HD film discs. Each one is a photographic transparency of a real sky, and each projects a completely different room.
What the discs cover
- Star fields. Dense, defined stars across the whole ceiling. The classic lights-off sky and the calmest choice for wind-down.
- The Milky Way. Our own galaxy edge-on, the band of light cities stole from us.
- The solar system. Planets you can name, which is where the bedtime astronomy questions start.
- Nebulae and deep space. The dramatic colour skies from telescope photography. Brightest and boldest, best for early evening.
- Saturn and friends up close. Single-subject discs that turn the ceiling into one enormous object.
Picking a sky for the moment
Wind-down and bedtime: star fields. Still, dim, sleep-friendly.
Movie-night backdrop: nebulae. Maximum colour.
Curious kids: the solar system, then answer questions until lights out for real.
Swapping takes seconds
Slide the current disc out, drop the next one in, done. No app, no pairing, no settings. The variety is the point: one fixed pattern gets old, 13 skies do not.
A note on honesty
Supplier materials for projectors in this category sometimes disagree on disc counts and features, so we verify what actually ships in the box and say exactly that. If anything changes, this page changes.

Quick answers
How many discs come with the Stellara Home Planetarium?
13 interchangeable HD film discs covering star fields, the Milky Way, the solar system, nebulae and close-up planetary skies. All are included in the box.
Can you change the sky on a galaxy projector?
Only on film-disc planetariums. Slide one disc out and another in. LED colour-wash lights have a single fixed pattern that cannot change.
Which Stellara disc is best for sleeping?
The plain star fields. They are the stillest, dimmest skies and suit the last hour of the day. Save the bright nebulae for earlier in the evening.
