- Honest reviewThe catch, not just the hype
Why this gift works
The Sega Toys Homestar Flux is a home planetarium that projects a star field of more than 60,000 stars through glass lenses with a 5 W LED. It comes with two discs - the northern sky with and without constellation lines - rotates slowly, has a 15, 30 or 60-minute timer, focuses from about 120 to 290 cm and runs on USB power.
It is far sharper than a toy star projector, which is why astronomy lovers and people who find the night sky calming both treasure it. For someone who lives under light-polluted skies, it is the closest thing to a dark-sky night at home.
Who is this gift for?
Great for
- An astronomy fan under city lights
- Someone who winds down under the stars
Think twice if
- They are a very light sleeper bothered by motor hum
The catch
It is expensive, the finish shows dust and fingerprints, the buttons are not lit, and the rotation motor can be heard by light sleepers.
Skip for someone who just wants a colorful mood light - a cheaper LED projector does that.

What to look for in a home planetarium
- Star count and sharpness. Glass optics and a high star count look far more real.
- Discs. Extra discs add the Moon, galaxies and seasonal skies.
- Noise. Rotating projectors have a small motor; check if they sleep lightly.
