If you're looking to represent a night sky for an authentic home planetarium experience, the Sega Toys Homestar Flux is your answer. However, it's also the most expensive product on our list at $259.

Why is this product so expensive? We can start with the build quality and components.

Using a patented photographic process similar to microfiche, the Homestar Flux uses analog removable discs with very high resolution, simultaneously showing as many as a million distinct stars. The product was designed in conjunction with Japanese astronomer/engineerTakayuki Ohira(TED Talk), the inventor of theMegastar, a professional laser-based planetarium projector that can show the most stars in the world. Sega (via its Sivesco subsidiary) has been in the home planetarium business since 2006. There are also third parties that also make discs for the unit besides Sega, such asMiller Engineering.

In addition to star fields, Sega also sellsHomestar discsrepresenting other astronomical formations, such as nebulas, galaxies, planets, and even jellyfish. I like using this product in the bedroom or on my covered patio because it's most usable at night in a very dark room, and its light projector is bright enough to see the star formations but not so bright as a laser that will keep you up at night.

The integrated timer is also suitable for listening to a sleep story for apps likeCalm, which have 30-minute audio segments. Unfortunately, you can't integrate the two because this product is purely mechanical, and there's no Bluetooth or WiFi integration with Alexa, Google, or Siri. There's also no way to control it remotely -- you have it set for "on" or in 15-minute, 30-minute, or 60-minute sessions.

Pros

• Bargain unit with accurate star projections
• Knockoff of the Sega Homestar Flux
• For relaxation purposes, it works great

Cons

• LED projector is only a fraction as powerful as the Sega unit
• You aren't getting as high-definition an image

Features:

• Attractive spherical industrial design only 12cm wide and 771g in weight (1.7 lbs)
• 1W warm white LED for projecting the optical image
• Smooth focus dial
• Counter-clockwise rotation
• 30-degree tilt adjustable from base
• 8-foot projection distance, 130 square roof projection area, 13ft image diameter
• Silent operation when rotating the star field
• Removable disc platter for use with POCOCO optical images (sold in packs of 5 for $49)
• Integrated timer for 15-minute, 30-minute, and 1-hour sessions and auto-off at 2 hours.
• USB chargeable and up to 6 hours of continuous use from the battery

If you are looking for a star projector with accurate star projections, complete with removable optical discs, but don't want something too expensive, I'd recommend the Pococo, which is effectively a more affordable knockoff of the Homestar Flux. It has some unique features, including the fact that it is Lithium Ion battery-powered and can run for up to six hours at a time on a single charge.

I also feel that it is a bargain at $99 for what the device does.

While I think the device is excellent for use in a bedroom (and in conjunction with apps like Calm), I don't think it's ideal for a larger living room or a patio because the LED projector is only a fraction as powerful as the Sega unit. Additionally, the optical discs that Pococo sells are perhaps a quarter of the size of the SEGA, so you aren't getting as high-definition an image, but for relaxation purposes, it works great.

Pros

• Inexpensive ($50 or less)
• "Nebula" combo laser and optical image projector
• Fantastic for accent or party lighting

Cons

• There are many similar or even rebadged products at this price point

Features:

• Galaxy light/starry sky "nebula" cloud projector
  
• Wi-Fi-enabled, voice assistant (Alexa, Google) integration, and home automation support.
• An app for fine-tuning the laser and nebula light intensity, color palettes, and scheduling.
• USB-powered, so you can use it independently of a wall socket with portable battery units.

For my home bar, I wanted something that would be more for entertainment rather than for relaxation purposes. I also was not so concerned with accurate depictions of the night sky. So, the star projector I ended up choosing was the Panamalar. It's under $35 with a promotion at Amazon.

Honestly, there are many similar products at this price point (I mention a couple later in this guide). Most of these units differ primarily in the shape of their plastic housing, and some are decorated with lights themselves. I chose this particular star projector because it was easily placed on a shelf and was unobtrusive.

If you look up "sky projector" or "laser star projector" on Amazon, you will find an entire category of products that are all very similar in design to the Panamalar. Most, if not all, appear to be made from a Chinese-built reference product and rebadged under different brands and even use nearly identical apps to control them.

They're all under $50, and they offer the following projection experiences:

• Laser-simulated star projector: This uses a bright green laser diode with a diffracting mirror to split the light into thousands of smaller beams to create a rotating simulated star field.
• Rotating optical nebula projection with multi-colored lights: This is a static, rotating image of a nebula star formation illuminated with a range of colors that can be set to progress through pre-configured and user-definable color "scenes." The nebula projection can be combined with the green laser star field, or each can be chosen individually.

These inexpensive star projectors are fantastic for accent or party lighting, and they are honestly a great deal at this price point. However, I find they aren't particularly good for relaxation purposes -- mostly due to the intensity of their lasers and their inability to represent an actual night sky.
