The reasonable price of this Orion telescope does not stop it from doing the task it is made for in an excellent way. You can expect a great experience from the superior Achromatic refractor the AstroView 90 equatorial refractor telescope comes with, plus excellent optics and unique accessory package, which contains the Sirius Plossl eyepieces, the finder scope, and the starry night software.

The AstroView weighs about 25 pounds and is almost 5 feet high making it quite big telescope, unsuitable for travel use, or at least it doe not fit in your suit case.

You can easily assemble the telescope as there are fully illustrated directions.

AstroView telescope boasts of classic design technology of refractors. This ensures you get high contrast and crisp planets and Moon views.
Every Sirius Plossl eyepiece provides detailed views essential for every astronomer. The low power 25mm delivers a 36X magnification to nicely frame the Moon. The second 10mm high power eyepiece provides a full detail of the Moon in crisp with a 91X magnification.

Deep sky objects are pleasure to view, thanks to the sharp optics brought by the Achromatic refractor. You will capture the ghostly glow of the Orion Nebula using the low power 25mm eyepiece on a moonless night. The Trapezium of Orion Nebula embedded by four stars is clearly visible through a 10mm Sirius Plossl eyepiece zoom.
Combining the 10mm eyepiece with Ultima 2X Barlow will deliver an 182X powerful magnification enough to get a clear view of the famous Great Red Spot of Planet Jupiter. So, there are plenty of options, and powerful magnification, which is in the most cases the reason to buy a telescope.

By pointing the polar axis simply to the North Star at Polaris, you can track celestial objects at high power. A slow motion knob can easily maintain the stars and planets in the view field when turned while the telescope is focused at the North Star. Also automatic tracking is possible with optional Electronic EQ-2M Telescope Drive offered by Orion. It is basically a battery powered moter for the automatic tracking. Electronic Hand controller has 2x and 4x speeds and pause mode. This is somewhat a great addition especially if you are planning to record videos.

For Who is the Orion Equatorial Refractor Telescope Suitable?

Beginners would find the telescope suitable, but the product would suit even better for more experienced astronomers. The impressive features can be utilized well by intermediate and advanced astronomers. Buying this kind of refractor telescope as a first telescope or upgrading to this model, makes sure that there are no need to buy a new telescope unless you are ready to move significantly higher price range.

The height and weight of the AstroView together with its design makes this not suitable for children under 12-years old.

How Does it Perform?

A powerful and high-quality telescope that will enable you to view deep-sky objects in crisp. This it owes to the 3.5″ aperture and a focal length of 910mm. You can view amazing details of the moon as well as the most planets. By combining the objective lens and the Sirius Plossl eyepieces of the AstroView, you are able to get clearer, brighter, and magnified images of the celestial.

You can use a manual tracking of the extraterrestrial in slow motion thanks to the EQ-2 adjustable tripod plus an equatorial mount included. A slow motion knob is provided. You ¨can keep the extraterrestrial objects in the view easily by turning this knob. Without this it would be easy to lose the object especially when greater magnification levels are in use.

Using a correct-image diagonal with the telescope it is fully suitable also for daytime earthly viewing, but it really shines in the night time use of universe.  A 90-degree mirror diagonal, 25mm and 10mm Sirius Plossl eyepieces, a 1.25 inches smooth-adjusting rack and pinion focuser, and a 6 by 30 finder scope offers great options.

When viewing the celestial, you can actually take shots of what you see as telescope comes with camera mounting attachments allowing easily connect a DSLR camera.

Price vs Benefits & Features

The magnification strength that allows you to view clearly very far away objects, and a unique accessory package with outstanding features, which all are designed for specific purposes, which harmoniously bring a superb performance, this telescope is more worthy than its price.

You will never expect sturdy high-quality material that withstands falls and hits from a telescope in this one’s price range, however this AstroView model can take some hit, and still function perfectly, thanks to it’s high-quality construction.

Again the crisp clear views you get of objects with this Orion’s 90mm EQ Refractor is unbelievable when considering its very reasonable price. Most telescopes with these features and power are much more expensive. So, if you are looking for a refractor telescope with great features, but reasonable price, that is your top choice.
