Celestron - StarSense Explorer 80mm Refractor Telescope - Silver/Black
- General
- Product Name: StarSense Explorer 80mm Refractor Telescope
- Brand: Celestron
- Model Number: 21074
- Color: Silver/Black
- Additional Dimensions
- Optical Tube Dimension Length: 965 millimeters
- Optical Tube Dimension Diameter: 90 millimeters
- Objective Lens Diameter: 80 millimeters (Generally, the larger the diameter of the objective lens, the greater the light-collecting power and the brighter images will appear.)
- Dimensions
- Product Height: 3.5 inches (The out of box height of the item. Height is measured as the vertical distance from the bottom of the item to the top as it would be primarily used or placed.)

- Product Depth: 38 inches (The out of box depth of the item. Depth is measured as the distance from the front of the item to the back as it would be primarily used or placed.)
- Product Weight: 5.4 pounds (The out of box weight of the item.)
- Included
- Eyepieces Included: 2x 1.25" eyepieces: 10mm, 25mm, 2x Barlow lens
- Tripod Included: true
- Material
- Material: Other
- 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.)
- Tripod Mountable: Yes
- Imaging
- Magnification: 189 times
- Exposure Control
- Focal Ratio: f/11 (Measurement of the device's optic "speed," calculated by dviding focal length by aperture. The smaller (faster) the f/number, the lower the magnification, wider the field of view, and brighter the image - good for low power observing and deep space photography. Larger (slower) f/numbers are better suited for high power lunar and planetary viewing.)
- Focal Length: 900 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: Manual (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.)
