- Brand: Celestron
- Model Number: 22460
- Color: Black
- Additional Dimensions
- Optical Tube Dimension Length: 945 millimeters
- Objective Lens Diameter: 90 millimeters (Generally, the larger the diameter of the objective lens, the greater the light-collecting power and the brighter images will appear.)
- Dimensions

- Product Weight: 14.2 pounds (The out of box weight of the item.)
- Included
- Eyepieces Included: 1.25" 10mm, 25mm eyepiece
- Tripod Included: true
- Case Included: false
- USB Cable Included: false
- Material
- Material: Other
- Performance
- Water Resistant: false (Resists some degree of water penetration.)
- Power
- Battery Size: Other (The battery size required for operation.)
- Features
- Magnification Type: Variable (Variable magnification indicates the presence of a zoom function on the device, but fixed magnification cannot be adjusted by the user.)
- Optical Design: Refractor (There are three primary optical designs for telescopes: refractor, reflector, or catadioptric. Refractors use lenses, reflectors use mirror(s), and catadioptric telescopes use a combination of both to form images.)
- Indicator Light(s): false
- Tracking Rates: Sidereal, Solar, Lunar (Refers to the speed of movement of the telescope's axis in order to follow a target of observation. There are several rates classified by a celestial object's apparent rate of motion: sidereal (star) tracking, lunar (moon) tracking, and solar (sun) tracking.)
- Tripod Mountable: Yes
- Imaging
- Magnification: 213 times
- Exposure Control
- Focal Length: 910 millimeters (The distance from an optical device's primary lens or mirror to the point where light rays come together in a single focused point, used to determine a device's magnifying power.)
- Other
- Telescope Class: Refractor
- Limiting Visual Magnitude: 12 (Measures the brightness of the object as determined from the naked eye (will be less than the same object's limiting photographic magnitude). The larger the magnitude, the fainter the item that can be seen.)
- Slow-Motion Control: Mechanical (For optimal tracking of astronomical objects, smooth and steady slow motion control is necessary. Manual control requires adjustments made by the user, while mechanical controls automatically adjust.)
- Resolving Power: 1 arc sec (Refers to the device's ability to distinguish detail between far away objects and separate distinct points of an object at small angular distances. The lower the arc seconds, the greater the ability to distinguish detail. Generally, resolving power increases as the diameter of the telescope increases.)
- Assembly Required: Partial
- UPC: 050234222013
