The satin black finish adds a premium touch, making it a stylish addition to any room. You’ll love how compact and stable it is, so you can place it anywhere without worrying about it tipping over.
Setting it up is a breeze. In just a few minutes, you’ll have your home planetarium ready to go. The intuitive controls make it easy to operate, even if you’re not tech-savvy. Plus, the focus ring ensures sharp projections, no matter the distance. While the satin finish does require occasional cleaning to keep fingerprints at bay, its durability and lightweight plastic construction make it a long-lasting choice.
Advanced Projection Technology
When it comes to projection quality, the Homestar Flux truly shines. This scientific star projector uses a powerful 5-watt LED bulb and advanced multilevel glass lenses to project up to 60,000 twinkling stars onto your ceiling or walls. The result? Astonishingly clear and vivid visuals that make you feel like you’re gazing at the real night sky.
The projector’s silent rotation mimics the natural movement of the stars, creating a calming and immersive experience. It works best in dark rooms but still performs well in dim lighting. With a projection distance of 140 to 270 centimetres and a surface coverage of up to 8.9 feet, it’s perfect for most spaces. The USB power compatibility also makes it easy to use anywhere in your home.
Shooting Star Functionality
One of the most enchanting features of the Homestar Flux is its shooting star function. Imagine lying under a blanket of stars and catching a glimpse of a meteor streaking across the sky. This feature adds a magical touch to your stargazing sessions, making them even more memorable.
The shooting star effect is designed to appear at regular intervals, adding a dynamic element to the otherwise static projections. It’s a small detail, but it makes a big difference in creating an authentic celestial experience. Whether you’re using the projector for relaxation, education, or ambiance, this feature is sure to impress.
Timer and USB Power Compatibility
The SEGA TOYS Homestar Flux makes your life easier with its thoughtful timer and USB power features. You’ll love how these additions enhance convenience and flexibility.
The timer function is perfect for winding down at night. You can set it to automatically turn off after 15, 30, or 60 minutes. This means you can drift off to sleep under a canopy of stars without worrying about getting up to switch it off. It’s a small feature, but it makes a big difference, especially if you’re using the projector as a relaxing bedtime companion.
The USB power compatibility is another game-changer. Instead of being tied to a wall socket, you can power the Homestar Flux using a laptop, power bank, or any USB-compatible device. This flexibility lets you set it up anywhere in your home, whether it’s your bedroom, living room, or even outdoors during a cozy evening under the stars. No need to rearrange furniture or hunt for an outlet—just plug it in and enjoy.
These features make the Homestar Flux not just a star projector but a user-friendly device that fits seamlessly into your lifestyle. Whether you’re using it for relaxation, education, or ambiance, you’ll appreciate how easy it is to operate and adapt to your needs.

The SEGA TOYS Homestar Flux takes stargazing to the next level with its expandable star disc collection. This feature lets you customize your celestial experience, making it as unique as your imagination.
The projector comes with two standard discs: one showing the northern hemisphere with constellations and another without. But why stop there? With over 30 additional discs available, you can explore a wide variety of themes. From scientifically accurate star maps to whimsical designs like jellyfish or hot air balloons, there’s something for everyone. You can even enjoy breathtaking views inspired by astronomical observatories.
This versatility makes the Homestar Flux a fantastic choice for both casual users and astronomy enthusiasts. Want to teach your kids about constellations? Pop in an educational disc. Looking to create a dreamy atmosphere for a party? Choose a novelty theme. The possibilities are endless.
By offering such a diverse range of options, the Homestar Flux ensures you’ll never get bored. It’s not just a star projector—it’s a gateway to countless celestial adventures.
Performance and User Experience
The SEGA TOYS Homestar Flux delivers an impressive visual experience. Its 5-watt LED ensures the stars remain bright and visible, even in less-than-ideal lighting conditions. You’ll notice the twinkling stars look sharp and vibrant in complete darkness, creating a truly mesmerizing effect. If you’re using it during the day or in a dimly lit room, the projections still hold up well, though darker settings bring out the best results.
Brightness and Projection Clarity
This star projector doesn’t just light up your room—it transforms it into a home planetarium. The clarity of the projections makes it feel like you’re gazing at the real night sky. Whether you’re using it for relaxation or to teach someone about constellations, the visuals are sure to captivate.
Put some music on and set it to rotate and you have a really beautiful way to relax under the night sky, no matter what the weather is like outside.
To add a little more life to the projection you can turn on the shooting star. This makes a brief appearance ever few minutes and then disappears. The shooting star is beautiful, subtle and doesn’t distract from the main projection, so is well worth turning on.
For those of you looking to increase your understanding of the night sky the Northern Hemisphere with constellation lines can help, it offers the same view but layers over visible lines so you can easily see different constellations and learn where they are in the night sky.
The technology in this puts out a strong and clear projection, I’ve found it works best on a flat surface without anything else, such as TVs, giving off light pollution.
Silent Operation and Adjustable Angles
The Homestar Flux is designed with your comfort in mind. Its silent operation ensures you can enjoy a peaceful stargazing session without any distracting noise. The faint whir of the device is barely noticeable, adding to the soothing atmosphere.
Here’s a quick look at how these features enhance usability:
| Feature | Description |
|---|---|
| Quiet Operation | The rotation simulates the night sky’s movement without making a sound. |
| Adjustable Stand | You can position the stand at any angle for a customized viewing experience. |
| Directional Rotation | The rotation direction can be reversed to simulate northern or southern skies. |
You’ll love how the adjustable angles let you project the stars exactly where you want them. Whether you’re lying on your bed or sitting on a couch, you can tilt the projector to create the perfect view. It’s all about making your stargazing experience as comfortable as possible.
Additional Projection Discs
Being the latest model in the established Homestar range has its advantages, unlike most low cost projectors the Homestar Flux has access to additional sky discs developed by the Japanese inventor and entrepreneur Takayuki Ohira:
- Southern Hemisphere
- Curved Andromeda Galaxy
- Earth and moon by day
- Earth and moon at night

Comparison to Other Star Projectors
Homestar Flux vs. Previous Models
If you’ve used earlier versions of the Homestar series, you’ll notice the Homestar Flux takes things up a notch. The upgrade from a 3-watt LED to a 5-watt LED is a game-changer. It delivers brighter and sharper projections, making the stars look more vivid and lifelike. The illuminated controls are another thoughtful addition, making it easier to operate in the dark. Plus, the premium satin black finish gives it a sleek, modern look that feels more refined than its predecessors. These improvements make the Homestar Flux a standout choice if you’re looking for the best star projectors in 2025.

| Projection distance | 150cm to 230 cm | 120cm to 290cm |
| Projection area | 270 cm | 290cm |
| Projection dimensions | 16 x 16 x 15cm | 16 x 16 x 15 cm |

| Power | Wall outlet | USB |
Homestar Flux vs. Competing Star Projectors
When you compare the Homestar Flux to other star projectors on the market, it’s clear why it’s a favorite. Here’s how it stacks up:
- The 5-watt LED provides brighter and clearer projections than many competitors that use lower-wattage LEDs.
- It’s designed with adults in mind, focusing on scientific accuracy rather than gimmicks.
- With over 30 compatible star discs, it offers more projection options than most alternatives.
While some competitors, like the National Geographic Home Planetarium, include extras like built-in speakers, they often sacrifice sleek design. Others, like the Bresser Junior Astro Planetarium, are more affordable but lack the clarity and quiet operation of the Homestar Flux. If you’re after a balance of quality, functionality, and style, the Homestar Flux is hard to beat.
Comparing Sega Toys Homestar Flux Planetarium and NEBULA by Anker Mars II Pro: Which Is Better for Home Entertainment?

And let’s not forget the expandable star disc collection, which keeps your stargazing experience fresh and exciting.

Very helpful demo clip, I’m looking at purchasing a unit like these. While the orig is not bright enough, I did prefer its depiction on the night sky (much more as we would see it with the naked eye). Now I’d like to find a unit that gives a better natural view of the night sky and is as bright as the Flux.
Both seemed to project in B/W (is that so or is this just as we see it on the demo?) I tend to prefer a deep blue sky with white or pale blue stars (is there perhaps a way of creating this effect with any adjustment controls on either of these two interesting units??) Many Thanks for any info you can supply.
Another most helpful demo clip, this one convinces me of the improved quality of the Flux. Is this the model that allows (or has the shooting star effect?) or have I confused this with another unit? Thanks for any added info you can supply.
The units just have a bulb in, the disc determines what colours are projected. You’d need to check out the available discs to see if any meet your requirements.
Both the original and Flux have shooting star effect.
