arrAbout Us

The Need for this Site

In recent years, astronomy review sites such as Astromart, Cloudy Nights, Excelsis, and a few others have done a fantastic job in letting us read and write reviews of astronomical telescopes and accessories. However, if you are searching for reviews on a specific product, most of these sites do not lend themselves to easy searches. If a review of a telescope you don't particularly care about contains a great paragraph of a mount that you are thinking of buying, there is a good chance you haven't seen it. And most of these sites don't let us add our opinions or short reviews - after all, not all of us have the time, inclination, experience or literary skills to submit a 2-page review of a product.

That is where comes in. We aim to complement - not compete with - these other great sites. Here, you can rate products, write your own short reviews, read other user reviews, link to product reviews on many other review sites, rate the content of other user reviews, and find places to buy products you're reviewing.

And to entice you to write reviews, we will offer frequent prize drawings for submitted content as well as offer discounts good towards astronomy goodies for every single review you write!

At, you can...

Read User Reviews
Reading product-based reviews is the best way of seeking guidance to learn more about astronomy products and before embarking on a shopping mission. The person whose advice you seek is neither a manufacturer nor an advertiser, but an amateur astronomer like you. Therefore, his opinion on a product is going to be without any preset motivation.

Read External Astronomy Reviews

You can easily link to product reviews elsewhere on the internet. We have scoured every single review on dozens of astronomy review sites, spent hundreds of hours and cataloged every product we could find, even if that product wasn't the main focus of that review. If there are forum discussions or reviews we've missed, we'd love to have you tell us about them so that we can add them to our site.

Rate Reviews
When you finish reading a review, you will find a link asking you to rate that review. Choose the option that best reflects what you think about that review. Your feedback helps the best reviews stand out, and makes it easier for others to find the most useful information easily. Besides user reviews, you can also rate the content on external review sites and product information/description at vendor links.

Write Reviews
Writing a review at is as easy as composing an email. By writing reviews based on your experience with the product, you will enable others to make judicious decisions about those products.

Earn Prizes and Discounts
We want to make it worth your while to spend time writing reviews and offering feedback at So for every single review you write, you will automatically receive a $3 off coupon good towards a $30 or larger purchase at Agena AstroProducts. You can combine coupons so you can get larger discounts. Write 10 reviews, and you've effectively earned yourself $30!

And that's not all. We will hold weekly and monthly drawings and offer fabulous astronomy prizes to the winners. Every review you submit earns you 25 points (like 25 raffle entries) for the random drawing. We will even ship the prizes to you at our cost.
