- Aperture: 80mm, providing more light-gathering power for better views of celestial objects like the Moon, planets, and some deep-sky objects.

- Focal Length: Typically around 600mm to 640mm, depending on the exact model variant, offering a moderate field of view.
- Focal Ratio: Generally f/7.5 to f/8, which is ideal for balancing detail and image sharpness, making it suitable for both visual observation and astrophotography.
