这是国外使用者的评价，真的这么差吗？

这是国外使用者的评价，真的这么差吗？



don't even think of buying this, August 18, 2006
By Ganesh Kumar Eswaran "Ganesh Kumar" (Lansdale, PA, USA) - See all my reviews
A piece of real crap. Never even think of buying this.

After lot of difficulties, I could finally point it to the moon. I only saw white light through its eye-piece as much as I can see with my naked eyes!!! The eye piece is so small, it seems as if I poked a hole on a piece of paper and watched a portion of the moon through the paper. And I paid so much money to see that crap?

Then I focussed on a distant star. It just appeared as it would appear through a 4x cheap binocular.

Believe me, don't buy a telescope if you live in a city and have enough "noise" from other light sources. If you live in a country side, you'd better buy a better telescope and not this crap.

I finally sold it on ebay and bought a good pair of Nikon binocular. The moon looks awesome through the Nikon binoculars. Read my other review on Nikon binoculars.

看这个价格，这么差也是正常的。

如果把博观天狼拿给外国人，恐怕评价也好不到哪里去！

这个应该会好些吧！其实celestron80ed是相当好的选择，只是价格略高一些！

以上价格都是美元，我想这些镜子都是国内OEM的，同样指标，在国内卖，价格却高得多，为什么会这样呢，国内的消费水平比美国低得多啊！！
