- Model Number: 21048
- Product Name: AstroMaster 70mm Refractor Telescope
- Color: Black
- Assembly Required: Yes
- Additional Dimensions
- Objective Lens Diameter: 70 millimeters (Generally, the larger the diameter of the objective lens, the greater the light-collecting power and the brighter images will appear.)
- Included
- Software Included: Starry Night Basic Edition; SkyPortal App
- Eyepieces Included: 20 mm eyepiece, 10 mm eyepiece
- Tripod Included: true
- Case Included: false
- USB Cable Included: false
- Material
- Material: Aluminum
- 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.)
- Mount Type: Manual alt-azimuth
- Tripod Mountable: Yes
- Integrated Digital Camera: false
- Multi-Coated Optics: true (Multiple lens surfaces are coated and/or have multiple layers of thin films applied to each. Generally, more lens coatings provide higher levels of light transmission, contrast, and color clarity.)
- Imaging
- Magnification: 165 times
- Exposure Control
- Focal Ratio: f/13 (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.)

- Telescope Class: Refractor
