If you’re looking for a home planetarium, there are two popular choices to consider. You have the Sega Toys Homestar Flux and the Sega Toys Homestar Original. They come from the same brand, but each of them has distinct features that will be discussed in this article.

Aside from that, I will compare these two products in terms of their set-up, functionality, quality, service or warranty, and price. And finally, you’ll find out which one is a better choice and why I recommend it.

Let’s begin with the start-up of these home planetariums. They have a common start-up, which only takes a few minutes. The device assembly is also the same.

The Homestar Flux takes two to three minutes to start working. The first thing you need to do is insert one of the two star discs by pulling out the front flap then inserting it back again. Use the cable to connect the room planetarium to a power source. Turn the unit on then adjust the sharpness to start viewing the starry skies.

Meanwhile, the Homestar Original takes a few minutes to start. You need to remove the protective cap first then connect the cable to a power supply. Insert one star disc by pulling out the front flap where you can see an opening. Once you have inserted the disc, insert the flap then press the power button to start the device. Use the wheel found around the lens to adjust the sharpness, and you’re all set. You can see a clear picture of the night skies.

Without a doubt, both units have outstanding features as a home planetarium. For one, the Homestar Original has a timer that automatically switches off the device after 15, 30, or 60 minutes. It’s also the same timer that you can see on the Homestar Flux. They also come with a LED light. It means that you can watch the starry night skies while lying in bed as fall asleep.

A shooting star function is present on both home planetariums, but the Flux is slightly updated and looks more realistic. It is activated when a shooting star appears. There is also a rotation function that rotates the device to the north or south. However, the Original unit doesn’t indicate to what direction it rotates, and it makes noises as it moves. The Flux, on the other hand, produces minimal noises in addition to having illuminated buttons that are visible in the dark.

The focus adjustment is an essential feature in a home planetarium. The frame best adjusts the focus on the Homestar Original, and it should be within a distance of 4.9 to 7.5 feet from the wall to the ceiling. With two discs, each having 60,000 stars, its projection only covers about 8.2 to 9.8 feet in diameter, but it doesn’t label the star images.

The Flux is a much better planetarium in terms of this functionality. Since it has a more extensive and sharper projection, it only has a minimal focus adjustment, which is adjusted through the focus wheel. It also has two discs, but each disc contains more than 60,000 stars.

From the looks of it, both home planetariums have the same functions. But between the two, the Homestar Flux has a much better projection, giving you a much clearer, sharper, and more realistic images of the dark skies. It’s also lighter than the Homestar Original.

When it comes to quality, there may be a slight difference between the two. The Homestar Original has a good quality finish with materials that make the device sturdy. It comes with a 3-watt LED light and a protective flap for the lens. Meanwhile, the Homestar Flux already exudes sophistication with its packaging. It comes in a white box decorated with silver prints and an additional black cover for added protection. The matte-colored planetarium is high-quality, high mass, and stable.


The Sega Toys Homestar Flux has fantastic quality.



Since the Homestar Original and the Homestar Flux come from the same brand, Sega Toys, it also has the same support or warranty service.

The good news is that it is easy for users to reach customer support if they have questions or encounter any problems with their units. There is a phone number that you can call and an e-mail address just in case you can’t reach them through their phone number. And the best part of it is that you get a fast response from the support team. I’ve had the first-hand experience with this, and the issue was resolved right away.

If you purchase a Sega Toys home planetarium online, there is a 14-day return policy in Germany. Aside from the right to return your order, you also have a warranty. The company offers a 2-year guarantee period, and that is not a problem. The units are sturdy and can last a long time; you won’t have to take advantage of the warranty.


Price Performance

Now, of course, this discussion will not be complete without talking about the prices of the products. Both home planetariums are not on the cheap side. The Homestar Original is around $140, and with that price comes a good quality device. Although some of its features are not at par with the cost, it’s still an excellent home planetarium for first-time users. It delivers and performs how the usual device works. With that said, the price performance of the Homestar Original is not justified.

The Homestar Flux, on the other hand, is more expensive than the Original, costing around $190. But the high price is for a good reason. It has more impressive functionality than its predecessor. All buttons are illuminated, which means you can see them even when there is no light. You get more than 60,000 stars. And best of all, it provides sharper and clearer images, which you don’t get from the Original. The price-performance? I would say that it is good, considering the impressive specifications of the device.


Conclosure – Sega Toys Homestar Flux vs. Original

There you have it, a comparison between the Homestar Original and Homestar Flux. Both devices have many similarities, but they also have significant differences.

They do have the same start-up, customer service support, and warranty period. But when it comes to their functionality, the Flux has better features than its predecessor. From illuminated buttons, minimal rotation noises to sharper starry sky images, it is clearly an updated version of the Homestar Original. And because it’s better, Flux is also more expensive than the original. In terms of packaging quality, Flux exceeds the Original unit with more security and protection.

But which of the two is the better option? I definitely recommend the Homestar Flux. Yes, it’s more pricey than the Original, but it’s worth the price. If you want a high-quality home planetarium that provides clearer images, then go big.

    Thanks for the review. When one has to buy more discs than what is originally given with the Flux edition, do you still buy whatever comes up ie if its for the original Sega will this still work on the Flux? or has the Flux got different discs to buy. Do you know where I can find a list of all the ones you can actually purchase? Thank you

    Hello and thank you a lot for this helpfull review !
    I’m still hesitating between these two models because the Flux is kinda hard to find.

    Anyway, my question is : looking for the homestar on Amazon.us, I find the “homestar classic” which seems to be different from the “homestar original”, some of them are also called “homestar pro”.

    Do you know about these models, and their difference?
    I’m looking for a home planetarium for my girlfriend as a Christmas gift, but I’m a bit lost!

    Thank you, cheers from France,

      Hi Louis,

      if you could find the Flux, I would always recommend it.

      As far as I know, the Homestar Original is an improved version of the Homestar Classic. And the Homestar Pro is just another name for the Original.

    Saw the disc link on Amazon.com for the Flux.
    I noticed these are the same pictures as offered by the much more expensive HS-1 projector made by Dark Skys.
    I also saw that microstru.com which is the same company as Dark Skys offers the same discs, but made especially for the Flux.

    Have you tried the discs sold on Amazon.com from KWELLER? Have you tried the Dark Skys discs for the Flux or Original?
    I’m wondering if the quality is the same since the price is so different when buying from KWELLER on amazon or from the original manufacturer.

    Thanks for your help!

    • Marcel Post authorReply

      Hi Brian,

      I don’t have any experience with the discs from KWELLER. But they look really similar to these from the manufacturer. So I guess you can buy them and try them out. In the worst case, you can send them back to Amazon.

    Thank you for all this helpful information.
    We purchased the sega flux for our 12 yr old grand daughter.
    We turned on the shooting star function but it does not seem to work .
    What do we need to do to fix this?

    • Marcel Post authorReply

      Hi Frani,

      I don’t know what is to do in such a case since my Homestar Flux works without any problems.

      Maybe you should ask the customer service of Sega Toys.

    Hi Marcel.
    Thank you very much for the excellent review.
    I’m am ready to buy one of these two planetariums.
    But I have a question that you might be able to help, it is the last detail that will help me decide which one to choose.

    I noticed that in many comparisons of images between classic and flux, the flux seems to have a smaller diameter and has a very visible border that limits the projection, when I see Classic images I don’t see this projection contour, does that really happen?
    because in all the features I am more focused on the flux, I see the images and I notice that the flux is much clearer and the quality is been improved, but it seems that everything is more condensed ,limiter and it gives the impression that the immersion in the space is a little bit lost in terms of area.
    I hope you understand my question.
    could you help me?
    thanks again for the excellent review

    • Marcel Post authorReply

      Hi Yuri,
      that is an excellent question. I will try to answer it:

      As you wrote, the quality of the Homestar Flux is much better. This also makes the borders of the projection a bit more perceptible. However, the difference at the border is not as noticeable as in the pictures. Here it looks like that because the projections were taken from different proximity. Otherwise, I would not have gotten the stars of the Original so well on the pictures. If you put the projection of the Flux on your ceiling, for example, the borders are less visible because the projection looks larger and thus somewhat blurred on the outside.

      Personally, I would always prefer the Flux to the Original if your budget allows it.

    Many thanks for the reply.
    I was always in doubt between the two, and it was just that detail that made me doubt, because I didn’t want to buy a model and regret it.
    Many doubts arose because in forums the projection area of ​​the flux is a little varied, some say it is smaller others say it is larger.
    Thank you very much I will follow your advice.
    already had in mind that the flux would be the best choice.

    I’m just wondering if you tried to use Dark Sky 1 before.

    as it is pricey and also produce 4 million starts.

    do you think Dark Sky 1 better than Flux if you tried both and what you recommend thank you.

    • Marcel Post authorReply


      I have not tested it yet because it is not available in my country. As soon it is available here, I will buy it and test it.

    Where is the Flux manufacured> China? US? Elsewhere? Howard

    • Marcel Post authorReply

      Hi Howard, unfortunately, I do not currently have the Homestar Flux at hand to check this. The manual is definitely made in China. I think this also applies to the home planetarium.
