One of the best star projectors now lowest-ever price this October Prime Day

The Pococo Galaxy Star Projector, now just $87 even cheaper at $79.99 on Amazon, is a brilliant way to transform any room into a planetarium. Even at full price it's a fantastic, portable planetarium but at $13 off, this is an absolutely stellar deal.

Editor's note October 8: You can get the Pococo Galaxy star projector even cheaper than Monday's already decent deal price at Amazon 20% off using the on-page voucher.

We think it's one of the best star projectors you can buy. Not only is it small enough to sit on a table or nightstand, but it's also rechargeable so as to be extra portable.

Unlike some star projectors, the Pococo Galaxy Star Projector projects scientifically accurate images of the cosmos, from planets to galaxies. It comes with two slides and you can purchase others to expand your planetarium's universe.

Its size and rechargeable battery make it super portable and you can buy extra slides to project other parts of the cosmos. We think it's one of the best star projectors out there.

As we noted in our Pococo Galaxy Projector review, it projects vivid images, even during the daytime, and it's ridiculously simple to operate. At this price, it's a great detail.

Alternatively, if you don't need your projector to be scientifically accurate, there's the BlissLights Sky Light Evolve, which is 10% off for Prime Day.

But when is Prime Day? This is the second event of the year, known as Prime Day in October or Prime Big Deal Days. It runs October 8-9 inclusive and is the last big deal shopping event before Black Friday and Cyber Monday at the end of November.
