SIGHTRON Stella Scan Opera Glasses Set for Stargazing, 2x40, Monocular/Binocular, SET052

- Compared to standard binoculars or monoculars, these binoculars have a lower magnification, allowing you to observe a wider range of stars. The low magnification and 40mm objective lens allow you to see fainter stars than you can see with the naked eye. - Made of durable, CNC-machined aluminum, they firmly maintain the optical axis for comfortable observation. - All air-contacting surfaces of the lens are coated with multi-layer coatings, minimizing light loss due to reflections on the lens surface and achieving a bright field of view. - Comes with a dedicated semi-hard case for easy portability. - This product includes a StellaScan monocular and binocular set. *Infinity may not be visible depending on your visual acuity. We recommend viewing with a visual acuity of 1.0 or higher. - Effective objective lens diameter: 40mm - Lens coating: Fully multi-coated - Eye relief: 10mm - Minimum focusing distance: Approximately 2m - Eye width adjustment range: 56.5mm-71.5mm
