When used correctly, binocular solar filters allow you to observe the Sun’s photosphere, including visible sunspots and surface detail. Binocular viewing can provide a more comfortable and immersive observing experience for some users.
High-quality solar film offers excellent contrast while keeping overall weight low. Film construction is ideal for portability and occasional use when handled and stored properly.
This filter set is intended for front-mounted use only on compatible binoculars. Always ensure that both barrels are fitted with filters before aiming the binoculars at the Sun.
Inspect both filters before each use and discontinue use if either filter is damaged or compromised. Ensure each filter is securely installed and cannot be dislodged during use.
Never look at the Sun through binoculars or any optical instrument without properly installed solar filters on both sides. This product is intended for solar viewing only when used correctly.
FAQs
Measure the outside diameter of the tube or barrel where the filter will slip on, using a ruler or calipers. Measure across the widest point for accuracy.
Measure the outside diameter (OD) of one barrel and select the size that matches that measurement.
If your measurement falls between sizes, choose the next size up. This ensures proper clearance and avoids forcing the filter onto the tube.
You’ll be able to safely observe the Sun’s surface, including sunspots and other visible features, depending on conditions and optics.
