Since the Orion AstroView 90mm Equatorial Refractor is in the 300$ range, there is not much to talk about in this part. It is a great, well-built telescope for the price. The only downside is, as impressive the aluminum tripod sounds like it may wobble at times. Especially when focusing on a specific sight. But this problem is very common and easily fixable.


The Orion AstroView 90mm Equatorial Refractor Telescope is a monster when it comes to budget telescopes. It is well made with quality materials, designed for precision and performance by an experienced company. It delivers perfectly in the planetary and deep space range, which makes it perfect for the intermediate and beginner astronomers. Orion didn’t disappoint on this model and it is a strong recommendation from us.
