  • Over 60,000 stars (that’s a lot)
  • 2 Disc and Poster Included
  • Expandable with more than additional 30 discs available for purchase
  • Interchangeable discs with the newer Flux if you ever want to upgrade
  • Very silent – in fact you can’t ever her the motor
  • Timer (15/30/60 minutes)
  • Falling Star Feature – very popular with adults and kids alike


  • Complicated to add it to a power bank, so it’s slightly less mobile than the Flux version
  • Less crisp star projections

A Japanese inventor, Takayuki Ohira, a well-known expert and hands on planetarium professional, created this home planetarium system. He is also known for making the Megastar Cosmos, which is the world’s most advanced planetarium and even mentioned in the Guinness Book of Records. It is safe to say that this is a quality product.

Clients query: Does it have to be placed in the middle of the room to cover the entire ceiling?

Answer: The angle can be adjusted. If the room is very large, it may not cover the entire ceiling. In a regular room, 15’W x 20’Lx 10’H, the ceiling is covered and the image continues half way down the walls. Pretty Good! If the maximum area is larger than 12’, simply use 2!

The main feature of this projector is that is projects an amazing blue nebulae (cloud) as well as stars. You have the options to project just the stars, just the nebulae or both as the same time. It also has the option of choosing to cycle through the light effects and the lights are dimmable. There is also a built-in 6-hour timer for projecting the stars and beautiful nebulae while falling asleep. 

The it’s price range, the BlissLights Sky Light is probably one of the best options on the market, however in this price range you have to expect the stars to look less realistic and another downside to this specific projector is the lack of a remote control.

After careful consideration, one reviewer of this product said that Sega Homestar was better. There’s something to be said for that. It really depends on what you are looking for. In My Room might actually be better for beginners. More educational than broadly entertaining for the whole family. It does have many agreeable features, even though it is a bit pricier than Sega. Clients who purchased this also bought Miller’s Planisphere for Northern Latitudes 35 degrees to 45 degrees. Relax and learn.

A simple addition to your relaxation toolbox may indeed be Home Aqua Planetarium. A busy, working mother who hardly finds the time for personal time, or even just a regular mom with never ending homework, may find this just the ticket for a mental get away.
