The Orion BX90 EQ 90mm mid-size refractor telescope is a great choice for serious beginners.
The wide-field optics of the BX90 EQ Refractor makes it easier to find objects in the night sky compared to longer telescopes. The refractor's substantial 90mm (3.54") objective lens collects much more light than typical starter scopes for brighter, more pleasing performance on a wide variety of interesting celestial objects.
The included EQ-1C equatorial mount comes with useful slow-motion controls which can be used to manually track objects as they appear to move across the sky. You can even add an optional EQ-1CM motor drive (sold separately) for hands-free tracking.
This special kit comes with everything you need to star stargazing right away. Two 1.25" eyepieces provide different magnification options right out of the box. Use the included 25mm Kellner for wide views at 24x magnification, and boost magnifying power up to 60x with the 10mm Plössl eyepiece when you want to take a closer look. The Orion BX90 EQ Refractor Telescope also includes a 90° star diagonal for comfortable nighttime viewing and a red-dot sight to help aim the telescope. The included Moon Map and Moon Filter will enhance your lunar viewing experience, and the Barlow Lens will double the power of your included 1.25? eyepieces. The Orion Star Target Planisphere will help you learn the location of popular celestial objects.
Once assembled, the entire BX90 EQ weighs 15.5 lbs. for easy portability.
With locations and names of over 260 features on the Moon such as craters, mountains, valleys, "seas" and more, the included Orion MoonMap 260 is a great tool for beginning astronomers. This detailed map will even show you where various spacecraft have landed on the Moon's surface! The whole family will enjoy looking at the Moon with the telescope, then using the MoonMap 260 to learn the names of the craters and other features observed.
Metal filter cell threads directly into the 1.25" barrel of your telescope eyepiece. Telescope eyepiece filter transmits only 13% of the incoming light, boosting contrast and ability to discern detail on the Moon. Perfectly neutral color will not alter the natural color of the Moon.
Doublet lens system is multi-coated for excellent transmission and the internal housing is baffled to eliminate unwanted reflections and increase contrast. Threaded for use with 1.25" Orion telescope eyepiece filters.
Simply dial in the date and time across the top, and Star Target shows you the sky overhead. Designed for use within 30-degree North and 50-degree North latitudes regardless of calendar year - shows locations of 100 star clusters, nebulas and galaxies for viewing with binoculars or telescope.

Beginner Level - Suited for a wide range of uses, these products are simple to operate and set up. Some initial assembly may be required depending on the type of product. Optical instruments with this rating will have very good optical and mechanical quality. Great for families, young people, and folks who don't want to mess with equipment and complexity. Beginning level telescopes will show you countless lunar craters, Saturn's rings and a myriad of star clusters and nebulae! Referring to the manual is recommended.
Intermediate Level - These products offer higher performance and more advanced features than Level 1: Beginner models. They typically take a bit longer to learn and need some set-up or adjustments. But anyone with the slightest technical bent will have no problem getting familiar with these models. Referring to the manual is recommended.
Advanced Level - These products provide the best performance but may require more skill to master and appreciate. Optical instruments with this rating have exceptionally fine optics and mechanics. Some are easy to use but might be on the large or heavy side. Some are intended for specialized uses. These products will appeal to the more technically inclined. Referring to the manual is highly recommended.
For telescopes, the optical diameter (also known as aperture) is the size of a telescope's main light-collecting lens or primary mirror, measured in millimeters or inches. Telescopes with larger optical diameters collect more light, which leads to an increase in brightness and image resolution compared to smaller instruments.
For binoculars, the optical diameter (also known as objective lens diameter) is the size of each of the front-facing objective lenses of a binocular measured in millimeters. Binoculars with larger objective lenses collect more light, which increases image resolution and brightness. Binoculars with larger objective lenses are recommended for low light situations, and binoculars with at least 50mm or larger objective lenses are recommended for pleasing astronomical observations at night.
Binocular lenses and prisms are often coated with anti-reflective material to minimize light loss as light travels through the multiple optical surfaces of a typical binocular. Coatings help maximize the amount of light transmitted through each glass surface of a binocular, so as much light as possible reaches the observer's eyes to provide a bright and sharp image.
Good lenses are at least "fully coated," with a single layer of magnesium fluoride coating applied to each air-to-glass lens surface. Multiple layers of coatings are even more effective; the term "multi-coated" means one or more air-to-glass lens surface has multiple coatings. "Fully multi-coated" optics are even better, meaning all lens surfaces have multiple layers of anti-reflective coatings applied for maximum light transmission and optimal image quality.
