Celestron - Cometron 114AZ 450mm Newtonian Reflector Telescope - White
- General
- Product Name: Cometron 114AZ 450mm Newtonian Reflector Telescope
- Brand: Celestron
- Model Number: 21079
- Color: White
- Additional Dimensions
- Optical Tube Dimension Length: 457 millimeters
- Objective Lens Diameter: 114 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: 53 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 Width: 18 inches (The out of box width of the item. Width is measured as the horizontal distance from one side of the item to the other as it would be primarily used or placed.)
- Product Depth: 32 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.)

- Compatibility
- Computerized Star Locator Compatible: false
- Included
- Eyepieces Included: 10mm, 20mm
- Tripod Included: true
- Case Included: false
- USB Cable Included: false
- Material
- Material: Plastic
- Performance
- Water Resistant: false (Resists some degree of water penetration.)
- Power
- Battery Size: Other (The battery size required for operation.)
- Features
- Computerized Hand Control: false
- 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: Reflector (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.)
- Electronic Red-Dot Projection Viewfinder: true (Locate astronomical objects more easily by using the electronic red-dot viewfinder, which shows unmagnified upright images. Wherever the telescope is pointed, a red dot or other symbol appears on the projection screen to help the user locate and focus on targets.)
- Indicator Light(s): false
- Mount Type: Manual alt-azimuth
- Tripod Mountable: Yes
- Imaging
- Field Of View: 0 degrees (The area of a target, measured as an angle from the location of viewing, that can be observed.)
- Magnification: 269 times
- Exposure Control
- Focal Ratio: f/3.95 (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: 450 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
- Assembly Required: Partial
- UPC: 050234210799

Q: Is viewing monocular or binocular?
A: The Cometron 114AZ uses one eyepiece at a time for monocular-like viewing.
Q: Where is this telescope made?
A: The Cometron 114AZ is manufactured in China.
Q: Is this suitable for a four year old, obsessed with the Solar System?
A: The Cometron 114AZ is a very good telescope for the family to use, but for a four year old child, he or she must have adult supervision at all times while using the telescope.
Q: Where can I purchase different size eyepieces?
A: https://www.celestron.com/collections/telescope-accessories
Q: Does this come in a case? Is it easy to travel with?
A: It does not come in a case but it can be easily transported in a vehicle. The tube can be removed from the tripod when transporting.
Q: How do you take the accessory tray off to transport the tripod piece?
A: To remove the Cometron 114AZ telescope's accessory tray, turn the tray counter-clockwise until the tray tabs unlock in place on the tripod.
Q: Planned use is to see ships from my balcony. How many miles out can I see these boats at sea?
A: On a clear day, you can see ships approximately 3 miles out to the horizon due to the curvature of the Earth.
