Spectrum Telescope Solar Glass Binocular Filter

This filter is designed for binoculars with an outside diameter (O.D.) measurement between 67mm and 73mm. It is specifically compatible with the Nikon Action 10x50 and Canon 15x50 Image Stabilizing models, but you should measure the outer housing of your objective lenses to ensure a secure fit.

Yes, this is a high-quality glass solar filter designed specifically for safe sun viewing. It blocks harmful solar radiation, allowing you to observe sunspots and solar activity without risking eye damage.

This product is sold as a single filter unit. If you intend to use it with standard binoculars, you will need to purchase two filters—one for each objective lens—to safely view the sun with both eyes.

Glass filters like this one typically provide a sharper, more neutral color balance compared to thin-film alternatives. They are also generally more durable and resistant to scratches, making them a reliable choice for frequent solar observation.

The filter is designed to slide securely over the objective lens housing. Ensure the fit is snug and stable before you begin your observation session to prevent the filter from slipping during use.
