Name: Cassini - 800mm Reflector Telescope with Electronic Wireless Focuser - White\Black
Brand: Cassini
SKU: 1654902
Rating: 4 (2 reviews)

Features
- Eye Relief: 20 millimeters (The maximum distance between the eyepiece lens and user's eye at which the full field of view can be seen.)
- 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
- Integrated Digital Camera: false
- Multi-Coated Optics: false (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.)
