The National Geographic Astro Planetarium is packed with useful features

国家地理天文天文馆充满了有用的功能

The Dark Skys Pocket Planetarium lacks some useful features

黑暗天空袖珍天文馆缺乏一些有用的功能

The Pococo Galaxy Star Projector lacks a speaker but offers plenty

Pococo Galaxy Star投影仪没有扬声器，但提供了很多

Starting this in-depth battle of pitting planetariums against each other, we'll take a look at the functionality and the features each of these three offers. These can help make a product stand out from the market by making it extra useful or versatile in its use and not just something that will project an image onto a wall.

开始这场天文馆之间的深入战斗，我们将看看这三个天文馆提供的功能和特性。这些可以帮助产品从市场中脱颖而出，使其在使用中变得更加有用或通用，而不仅仅是将图像投射到墙上的东西。

Right off the bat, the National Geographic Astro Planetarium is a stand-out for features and functions. It offers many useful things like rotation, a speaker, and a sensible sleep timer. The rotation can help people relax while looking at projections and stop the feeling of "is that it!?" after turning the projections on. The speaker requires a connection through a cable, as it isn't Bluetooth compatible and it has a built-in radio.

国家地理天文天文馆在特色和功能方面非常突出。它提供了许多有用的东西，如旋转、扬声器和智能睡眠计时器。旋转可以帮助人们在看投影时放松，停止“是这样吗！？”打开投影后。扬声器需要通过电缆连接，因为它不兼容蓝牙，而且它有一个内置收音机。

The sleep timer can be set to 30 or 60 minutes, so if you do choose to sleep with this on, you don't have to worry about it running all night. It also features a focus wheel, which is easy to use, and a disk tray, so you can insert one of the two disks included.

睡眠定时器可以设置为30或60分钟，所以如果你选择开着它睡觉，你不必担心它会整夜运行。它还具有一个易于使用的对焦轮和一个磁盘托盘，因此您可以插入随附的两个磁盘中的一个。

The Dark Skys Pocket Planetarium doesn't share the same useful features of the National Geographic model, but then again, it's not designed to. It does offer image rotation, but that's about it. There's no sleep timer, speaker or remote control. But it will fit in your pocket and it will offer images of Northern Hemisphere constellations. It's far more lightweight and its class two laser and silent operation make it a decent choice for those looking to relax in a darker room.

黑暗天空袖珍天文馆没有国家地理模型的有用功能，但话说回来，它的设计也不是这样的。它确实提供图像旋转，但仅此而已。没有睡眠定时器、扬声器或遥控器。但是它可以放在你的口袋里，它可以提供北半球星座的图像。它的重量要轻得多，它的二级激光和静音操作使它成为那些想在黑暗的房间里放松的人的不错选择。

Then there's the Pococo Galaxy Star Projector. A surprise when we reviewed it for sure as it gives some of the premium models a run for their money. In terms of functions and features, it offers a sleep timer that can be set to 15, 30 or 60 minutes and a two-hour auto shut off, so there's no fear of it running through the night. It also offers image rotation, which many will see as a positive.

然后是Pococo银河星空投影仪。当我们审查它时，这肯定是一个惊喜，因为它让一些高端型号物有所值。在功能和特点方面，它提供了一个睡眠定时器，可以设置为15、30或60分钟，并在两小时内自动关闭，所以不用担心它会整夜运行。它还提供图像旋转，许多人会认为这是一个积极的。

What it lacks, though, is a remote control or app, so it can only be controlled by the buttons on the unit itself. It also doesn't have a speaker, so if you're looking to unwind to music or a podcast, you can't do it through the projector itself. However, these aren't terrible omissions given its quality of projections and realistic imagery, which we'll get onto shortly.

然而，它缺少的是遥控器或应用程序，所以它只能通过设备本身的按钮来控制。它也没有扬声器，所以如果你想听音乐或播客放松，你不能通过投影仪本身。然而，考虑到它的投影质量和逼真的图像，这些并不是可怕的遗漏，我们很快就会谈到这一点。

National Geographic's projections are true to the chosen date/time

《国家地理》的预测与所选日期/时间相符

Dark Skys projections are realistic, but only of the Northern Hemisphere

黑暗天空的投影是真实的，但仅限于北半球

Pococo offers realistic imagery through disks

Pococo通过磁盘提供逼真的图像

Above all else, what makes a good projector is how good its projections are. It's the fundamental quality in a projector and all three of these perform well. A planetarium should project realistic images of the night sky as opposed to a regular star projector, which can get away with space-like projections and lasers that mimic stars.

最重要的是，一台好的投影仪取决于它的投影有多好。这是投影仪的基本品质，这三者都表现良好。天文馆应该投射真实的夜空图像，而不是常规的星空投影仪，后者可以通过类似太空的投影和模拟恒星的激光来逃脱惩罚。

The National Geographic again is the stand-out thanks to its ability to project images true to a chosen date and time. When the unit is positioned to face North, you can use a dial to select a specific date and the projector will project what the night sky will look like that night. It will use LED bulbs to project the vivid imagery and a focus wheel can be used to make the images appear as clear as they possibly can. Overall, the National Geographic scores very well here.

《国家地理》再次脱颖而出，这要归功于它能够在选定的日期和时间投射真实的图像。当设备面向北时，您可以使用刻度盘选择特定日期，投影仪将投影当晚的夜空。它将使用LED灯泡来投射生动的图像，对焦轮可以用来使图像看起来尽可能清晰。总的来说，《国家地理》在这里得分很高。

Then there's the Dark Skys model, which does project realistic imagery and is therefore a good option if that's what you're looking for, especially if you want portability too. Unfortunately, it doesn't quite possess the same power or brightness as the National Geographic. It will project images of Northern constellations onto any surface and you can opt to have an overlaying star map projected too. But, you will need prior knowledge to know exactly what you're looking at and you will need to be in a dark environment as the projections aren't the brightest available.

然后是黑暗天空模型，它确实可以投射逼真的图像，因此如果这是你正在寻找的，特别是如果你也想要便携性，这是一个很好的选择。不幸的是，它不像《国家地理》那样拥有同样的力量或亮度。它会将北方星座的图像投影到任何表面上，你也可以选择投影叠加的星图。但是，你需要事先的知识来确切地知道你在看什么，你需要在一个黑暗的环境中，因为投影不是最亮的。

Pococo's offering to this head-to-head-to-head again delivers the goods, this time for its projection quality. Its use of LED lighting allows it to project the images from its many disks onto any surface clearly and brightly enough. While it doesn't quite match the power of some high-end projectors, it more than holds its own. The good news is that there are loads of disk packs available, meaning the Pococo can clearly project many different images, with a projection surface of 12 square meters, or about 130 square feet.

Pococo的产品再次交付了货物，这一次是因为它的投影质量。它对LED照明的使用使它能够将图像从许多磁盘清晰明亮地投影到任何表面上。虽然它与一些高端投影仪的功能不太匹配，但它不仅仅是自己的。好消息是，有大量的磁盘包可用，这意味着Pococo可以清楚地投影许多不同的图像，投影表面为12平方米，或约130平方英尺。

The National Geographic is good value, if you can get a good price

如果你能得到一个好价钱，《国家地理》是物有所值的

The Dark Skys is comfortably the cheapest option here

黑暗的天空是这里最便宜的选择

Pococo is often on offer and costs similar to the National Geographic

Pococo经常提供，费用与国家地理相似

Finally, we move on to the business end of the article, the price. How much is each set going to set you back and are they really worth it? In short, yes. You do actually get quality when you buy these models.

最后，我们转到文章的商业部分，价格。每套要花你多少钱，真的值得吗？简而言之，是的。当你购买这些型号时，你确实得到了质量。

The National Geographic Astro Planetarium shouldn't really cost you any more than $110, and if you're lucky, you can get it below $90. It gives you real quality with quality projections, a sleep timer, a speaker and the ability to see night sky targets on any given date.

国家地理天文天文馆的价格不应该超过110美元，如果你幸运的话，你可以在90美元以下买到。它通过高质量的投影、睡眠定时器、扬声器和在任何给定日期看到夜空目标的能力为您提供真正的质量。

The Dark Skys Pocket Planetarium should set you back about $45, which is considerably less than both the National Geographic and the Pococo models. It's pretty neat as it works perfectly well in dark conditions, fits in your pocket and doesn't need to be powered by the mains. The only downside to it is that the other two can be made portable thanks to being battery-powered. Still, though, it's perfectly good on its own.

黑暗天空袖珍天文馆应该花费你大约45美元，比国家地理和Pococo模型都要便宜得多。它非常整洁，因为它在黑暗的条件下工作得非常好，适合放在你的口袋里，不需要电源供电。它唯一的缺点是，由于电池供电，另外两个可以便携。尽管如此，它本身还是非常好的。

Lastly, the Pococo Galaxy Star Projector. You can often find it on offer for less than $80 on several occasions. It's great value and can rival the premium models, even if it doesn't quite stand up to them. It has a sleep timer, rotation, realistic imagery and an LED bulb. There's a lot to like and it costs a similar amount to the National Geographic.

最后，Pococo银河星空投影仪。你经常可以发现它在几个场合以低于80美元的价格出售。它物超所值，可以与高端型号相媲美，即使它不能完全对抗它们。它有一个睡眠定时器，旋转，逼真的图像和一个LED灯泡。有很多值得喜欢的东西，价格和《国家地理》差不多。

Overall, as nifty as the Dark Skys model is, and as handy as its lightweight and pocket design is, we're looking to figure out the best of the best.

总的来说，尽管Dark Skys模型很漂亮，尽管它的轻量级和口袋设计很方便，但我们希望找出最好的。

In short, the National Geographic Astro Planetarium takes the crown. It has all the features you want, has quality projections and the ability to show you what the night sky will look like on any given date is just too irresistible. It's even in the same price range as the Pococo, which is a not-too-distant second.

简而言之，国家地理天文天文馆摘得桂冠。它拥有你想要的所有功能，有高质量的投影，并且能够向你展示任何给定日期的夜空是什么样子，这太不可抗拒了。它甚至与紧随其后的Pococo处于同一价格范围。

Both the National Geographic and the Pococo have their pros and cons, but both can rival some of the heavy-hitters in the star projector world and neither costs anywhere near as much.

《国家地理》和《Pococo》各有利弊，但两者都可以与明星投影仪界的一些重量级人物相媲美，而且成本都没有那么高。
