The Celestron LCM90 is a good-sized and well-equipped refractor at a very sensible small-scope price. The Celestron LCM90 is a wide-angle scope you can use day or night, for years to come, without ever running out of fascinating things to see on the land and in the sky.
You don’t have to know anything about right ascension and declination or how to find the north celestial pole or how to read a star chart to find your way around the sky with the Celestron 90LCM 90mm go-to refractor. Its easy SkyAlign alignment technology and StarPointer red dot LED finder make lining up on the sky a breeze. Once aligned, the scope’s NexStar-technology computer hand control will find more than 4,000 celestial objects for you and will track them unerringly while you observe at your leisure. With its pre-assembled adjustable height aluminum tripod and easy no-tool assembly, the light-weight Celestron 90LCM can be up and ready to take you on a tour of the Universe in a matter of minutes.
The Celestron 90LCM is a good choice for a beginning astronomer who wants to do some more-than-casual looking at the heavens, but at a surprisingly inexpensive price. This Celestron 90LCM has 90mm achromatic refractor optics with 225% more light gathering capacity than the more common 60mm scope. That means visibly brighter deep space images and the ability to see many more faint objects than a 60mm scope could ever hope to show. It has 50% higher resolution than a 60mm scope as well, to let you see more sharper and detailed views of the Moon, planets, binary stars, and star clusters at night and wildlife during the day.
The Celestron 90LCM has all the features and optical performance needed to keep a casual backyard astronomer family happily observing for years to come, at a price that is surprisingly affordable for all the computerized features it gives you. And it can be used for terrestrial observing, too – birdwatching, scanning the scenery from the home with a view, and more.
Detailed information about this product's features  LCM Mount
 LCM Computer
This Telescope’s Optical System . . . - Achromatic refractor optical system: 90mm aperture (660mm focal length f/7.33). The aluminum optical tube is connected to the mount by a no-tool quick release dovetail for fast assembly. Fully coated optics for high light transmission and good contrast. A good-sized lens shade is provided to shield the lens from ambient light for improved contrast and retard the formation of dew for maximum uninterrupted observing time.
- Finder: StarPointer non-magnifying variable brightness illuminated red dot finder on a quick-release dovetail mounting bracket. The StarPointer is a quick and easy way to point your telescope exactly to the desired object in the sky or on the ground. There’s no need to worry about the inverted images you see through traditional finders. Just align the red dot seen in the StarPointer with the desired star in the sky and you’re done.
- Focuser: 1.25" rack and pinion.
- Star diagonal: 1.25" 90° erect image prism that shows you celestial and terrestrial sights oriented the same way you see them with your bare eye. There's no confusing image reversal or inversion as you get with many other astronomical telescopes.
- Two 1.25" eyepieces: The first is a 25mm providing a magnification of 26x. The eyepiece field of view is 1.6° across, more than three times as wide as the full Moon for expansive views of globular star clusters and terrestrial observing. The second is a 9mm (73x) with a 0.6° field for more close-up views of the Moon, planets, and globular star clusters.
This Telescope’s Mount . . . - Fork mount/drive system: Single fork arm altazimuth design with pre-installed enclosed dual DC servo motor drives. A compartment in the drive base accepts eight user-supplied AA batteries for powering the telescope. An optional AC adapter and rechargeable battery pack are available to conserve battery life. For more details, click on the “mount" icon above. Usable day or night, this wide-angle 90mm LCM scope can be used to observe wildlife and sights on the ground during the day, as well as the Moon, planets, star clusters and more in the sky at night. Light enough for a youngster to take out on their own, this is a scope that will get more family use than you might expect.
- LCM computer control: The supplied NexStar-technology computer hand control has an illuminated numeric keypad and a two-line 16-character LCD display. It has a database of 4,033 stars and objects it can find and track for you, including the complete Messier and Caldwell catalogs of famous deep space objects; a selection of the brightest and best deep space objects from the Revised New General Catalog (NGC); selected SAO stars, including the best variable stars and multiple star systems; the planets; the Moon; the Sun; and more.
When you are ready to observe, simply input the date, time, and your location into the LCM computer hand control and use the StarPointer red dot finder to point the telescope at any three bright stars, or to two stars and a bright planet or the Moon. The LCM computer system will automatically align itself on the sky. Then, a few keystrokes on the LCM hand control and the computer automatically will slew your scope to any of the 4,033 objects in its memory you choose and track it so you can observe at your leisure. You can find hundreds of fascinating deep space objects your first night out, even if you have never used a telescope before. No matter what level of experience you start from, your LCM scope will unfold all the wonders of the Universe for you, your family, and your friends. For more details, click on the “computer" icon above.
- Supplied software: The scope comes with a CD-ROM of TheSky X – First Light Edition planetarium and star charting software. This program is a computerized sky map that features a 10,000 object database, 75 color images, horizontal projection, custom sky chart printing, and zoom capability. It will let explore the Universe on your PC or Mac and print out custom star charts of the sky to help you find faint objects that are not in the LCM computer’s database.
You can also add optional NexRemote telescope control software to allow you to more completely control the scope from your personal computer or laptop so you can keep your eyes on the stars instead of the hand control.
- Adjustable height tripod: The preassembled tripod has aluminum legs to damp vibrations quickly. The center leg brace holds a convenient no-tool quick-release accessory tray to keep your eyepieces and accessories up and out of the dew-soaked grass.
- Two-year warranty: All Celestron telescopes have a two-year warranty, double that of competitive scopes.
