Features
- Computerized Hand Control: true
- 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: Catadioptric (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.)
- Mount Type: Computerized alt-azimuth
- 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: true
- 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: 213 times
Exposure Control
- Focal Length: 1250 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.)
