In manufacturing and research, "6.5" often refers to the or zoom ratio of an objective lens, paired with a digital camera system. 6.5 Metre 1080P
For context, the famous JWST also uses a 6.5-meter primary mirror to capture infrared light from the early universe. 6.5 Metre 1080P
In the world of astronomy, a aperture is a massive milestone. It refers to the diameter of the primary mirror, which determines how much light the telescope can "bucket" from deep space. 6.5 Metre 1080P
