There are many, many different amateur telescopes on the market. Some are small and some are large. Some are portable and some are stationary. Some are cheap and some are expensive. Some are best for beginners, and some are designed for the very serious, very experienced amateur astronomer. Regardless of where you are on the spectrum, what you are looking for, what your budget is, or what you truly want, there is probably a telescope that will fit your needs, or at least come pretty darned close. But it’s not possible to research every single telescope supplier and look into every single telescope—that would be pure madness. But there are ways to find the information you need to help you make your decision. The best way to get this information is to look up telescope reviews.
There are many different places to find reviews. The leading science and astronomy magazines have regular reviews about the newest telescopes. They will discuss many different aspects of the telescope, like the power, the magnitude, the comfort, and the ease of use. Since there are many different brands, there are many differences between all of them. Though the basic model of the telescope doesn’t change, the reviews will tell you just how these telescope brands differ, why they differ, and how those differences might impact you. You can also find telescope testimonials online, through various amateur websites and communities. People who regularly use telescopes will have their own opinions and will be happy to share those opinion if you do a little research or ask around.
