Setup & Ease of Use

As a whole, setting up the Homestar Classic and Homestar Flux is a breeze. Sega did a fantastic job of making these two projectors as foolproof as possible. They're relatively uncomplicated, requiring only a few minutes to get up and running.

Starting the systems is a matter of plugging them in and flipping the switch.

There are some slight differences here. With the Homestar Original, you'll need to plug one end of the power cable into the projector and the other into a standard 120-volt outlet. Then, you'll have to remove the included lens cap.

For the Homestar Flux, you have a little more flexibility with power. You must connect the USB cable to the Flux and a power source. It does come with a standard power adapter. However, you can also use a power bank or computer.

You'll notice that both control panels are nearly identical. Not only that, but they're minimalistic in design. The Homestar line doesn't have overly complicated features or a ton of adjustment parameters. As a result, Sega kept things streamlined and to-the-point. The buttons are self-explanatory and even include small LED indicator lights for simplicity.


Now, let's talk about some of the included features.

Both the Original and the Flux utilize an image-based projector system. They don't rely on lasers to create an artistic depiction of our solar system. Instead, you're getting film discs that you pop into the projector like a CD! Both devices have a small tray that ejects from the base for easy insertion.

You get the same two discs with the Original and Flux planetariums. They include true-to-life images of the night sky in the southern and northern hemispheres. Sega also makes additional discs that you can purchase separately. They're all compatible with the Homestar Original and Homestar Flux. With more than 30 discs to choose from, you can expand your collection and add more variety to your simulated star shows.

Both systems also have a shooting star function. It's a feature that sets the Sega Homestar line apart from competitors. When initiated, these star projectors will create meteor falls at random. They appear sporadically, much like they do when you're stargazing in real life.

The feature works well in both the Original and Flux systems. But, we have to say that the Homestar Flux looks a bit better. It's updated and looks more realistic. That's not to say that the Homestar Original is terrible. But, it's evident that Sega refined the feature for the release of the Flux.


Once again, the Homestar Classic and Homestar Flux are neck and neck here. They include the same core functions.

To push the realism even further, you can set the image to rotate to the left or the right. The changing directions reflect the experience stargazers have in the northern and southern hemispheres. You can turn the rotation feature on and switch directions with a press of a button.

Now, the only main difference with the rotation feature is the level of noise produced. The Homestar Original is a bit louder than the Flux. The sound isn't exceedingly distracting. In fact, you might not even notice it unless you're sitting right next to it. However, that noise does exist! It comes from the gears that rotate the image disc.

Sega refined the system a bit with the Flux, resulting in an even quieter operation.

In addition to rotation features, you can also set a timer. Both the Original and Flux planetariums have 15, 30, and 60-minute timers.


Performance capabilities are where the Homestar Original "Classic" and Homestar Flux differ the most. Both systems are top-notch and very deserving of the praise they get. However, the Homestar Flux tends to perform better across the board.

Let's start with brightness. The Original planetarium features a 3-watt LED light to project the image. It does well in dark environments. But, you might experience some issues if light pollution gets into the mix.

The Homestar Flux uses a brighter 5-watt LED. It performs nicely in a wide array of environments. However, dark rooms are always best!

Performance features don't start there. The Homestar Flux is sporting a premium, multilevel glass lens. It improves brilliance, overall color vibrancy, and sharpness. There's no denying that it's far superior to the standard plastic lens of the Homestar Original. Glass optics will always trump plastic.

Both devices have a focus ring around the lens as well. Though, the one on the Flux seems to be a little more proficient. Paired with the glass lens, the focuser gives you greater flexibility in terms of projection distance and image size. With the Flux, you can be between 47 and 114 inches from the wall to get a clear image. The biggest image you can project is an enormous 114 inches in diameter!

The Homestar Original is not as capable. Yet, it's still impressive. Prime projection distance falls between 59 and 90 inches. The largest image you can create is 106 inches in diameter.

Build Quality

When it comes to the build quality, both Homestar systems are pretty impressive. They take on a spherical shape, which is unique for planetarium-style projectors. Both also sit on a sturdy wire base that's easy to adjust.

The Homestar collection is not outdoor-friendly. Make no mistake: These gadgets will break or experience damage if you attempt to use them in inclement weather. However, they should be fine with normal indoor use. The housing is made of plastic. While not the most luxurious material out there, the plastic is thick and rugged enough to keep the internals safe from light bumps.

As for the finish, the Flux is a little more premium. When you put the two models side by side, you'll notice that the Flux has a high-quality satin black finish. It's smooth and feels nice in hand. The Original has a more traditional plastic finish. The device also has a smooth finish, but it's noticeably shinier than the Flux.

What's In The Box?

Both galaxy lamps have everything you need to get started. But, there are some small variations in packaging and contents.

With both systems, you get an educational poster and the two same image discs. Of course, instruction manuals and some safety literature is included, too.

The Homestar Original "Classic" comes with a simple power cord. One end connects to the projector itself while the other plugs into a standard wall outlet. You also get a lens cover to protect the plastic optics from scratches and debris.

The Homestar Flux includes a USB cable. One side connects to the projector as usual. But the other is a USB dongle that you can use as you see fit. Connect it to a power bank for portability, or use it with a computer for simplicity. The system also comes with a power adapter if you want to keep things simple.

Interestingly enough, the Homestar Flux doesn't come with a lens cap like the Homestar Original. It's an interesting choice considering that the lens on the Flux is glass.

Despite that oddity, the Homestar Flux has one other interesting strength. The packaging is much better on the Flux than it is on the Original. The Original unit has a well-designed box, too. But it's simple and doesn't contain too many design features that pop.

The Flux, however, is housed in a white box that features silver lettering and print accents. Over that, a black sleeve keeps everything protected. The sleeve is black and features a spattering of stars, simulating the show you will experience. It's a beautiful design that works well for gifting.

Customer Service & Warranty Information

Because both units come from Sega, the customer service and warranty information are identical.

Both systems come with a generous two-year warranty. The policy has specific terms and stipulations that you should familiarize yourself with. Essentially, Sega will repair or replace the projector if manufacturer defects cause issues.

If you ever need assistance beyond returns or warranties, Sega has a top-notch support team. You can get in touch in several ways. The official Sega Toys website for the Homestar has a contact form, an email address, and a telephone number.

The customer support department seems to be quite responsive. They're active on marketplace sights and provide timely responses to queries.


The Homestar Original "Classic" and Homestar Flux are both worthy investments. They're fantastic devices that outperform many of their competitors.

Overall, these two devices are cut from the same cloth. The Original was the first of the lineup. It captivated amateur astronomers upon its release and continues to be a viable choice for many. However, Sega released the Homestar Flux as a follow-up. This model takes everything great about the Original and cranks it up! It's brighter, more capable, and has better image quality.

The Homestar Flux is the clear winner between the two. If you're looking for a high-quality planetarium experience in the comfort of your own home, you can't go wrong with the Flux!
