Assembling!!!

Being a refractor the biggest advantage of Orion Astroview 90mm telescope has the process of assembling the telescope is very easy. You are not going to get through the confusing process of collimation like in reflector. With the help of easy to follow instruction manual provided in the box, it will not take more than 10 minutes to make the telescope ready to use.

Review & Pros

Orion AstroView refractor features a multi coated aluminum tube with an objective lens diameter of 90mm and focal length 910mm with f ratio f/10.1, specification makes this telescope best suited for viewing the celestial objects near to us like Earth, Jupiter, and some other stars.

Orion AstroView 90mm Telescope provides clear, sharp and high contrast view of objects that even reflector telescope having the same 90mm aperture will not provide.

Astroview 90mm refractor comes with two different eyepieces of 25mm and 10mm aperture. These eyepieces help to magnify the object. A low power Plossl 25mm eyepiece provides a magnification of 36x while a 10mm eyepiece further improves the view with its 91x power. Let’s just say you are trying to view the moon, use 25mm eyepiece to nicely frame the moon and if you want to get even further and take a close up look at moons spot use 10mm eyepiece.

Highest useful magnification of AstroView 90mm refractor is 180x. to get the clear view the famous red spot on Jupiter or to get the clear view of Jupiter’s moon buy a 2x Barlow lens in future and use it with 10mm Plossl eyepiece to increase the magnification to 182x.

The package also contains a 90degree star diagonal which forms the image right side up. A very important feature if you intend to use the telescope for terrestrial viewing also.

To easily keep track of the objects when they move in the sky Orion AstroView feature an equatorial mount. Just align the telescope to Polaris, once the object is located keep track of that by simply turning the knob wheel. A simple, smooth and accurate process.

 

Cons

Equatorial mount wobbles a little bit when legs of the tripod are fully extended. The main reason for this is because the tripod is made up of aluminum, not steel. This problem can be solved later by upgrading to the high-quality steel tripod.

The weight of 23.7kg makes this telescope a little bit heavy to move or carry around for anybody.

 

Our final verdict

High-quality optics and strong build are USP of this telescope. In fact, we were so impressed with this Orion AstroView 90mm refractor that we had to include this telescope in our “The best telescope for beginners list” this year.  If you are interested in astronomy and have a budget of about 300$ then this is a good choice for you. Overall one of the best beginner’s refractor telescope you can get for this money. Just go for it without thing twice, you can never go wrong with this.
