How do I attach the 50mm Universal Lens Filter to my binoculars?
The filter is made of pre-scored heavy card stock that you fold into a cup shape. This cup is designed to fit snugly over the front barrel of your binocular's objective lens. Simply place one filter over each of the two 50mm lenses to begin observing safely.
Is the Universal Lens Filter's film safe for my camera sensor?
Yes. The Thousand Oaks SolarLite film is a "white light" filter that is placed in front of the lens, blocking 99.999% of the Sun's energy before it enters the optical system. This protects not only your eyes but also your camera's sensitive sensor and internal components from heat and intense light.
Can I use the 50mm Universal Lens Filter to see solar flares or prominences?
No. These are white-light filters designed to show the Sun's surface (photosphere), which includes features like sunspots and granulation. Viewing solar flares and prominences requires a specialized, narrow-band Hydrogen-alpha (H-alpha) telescope or filter, which isolates a specific wavelength of light from the Sun's chromosphere.
What makes this Universal Lens Filter bundle a good choice for a solar eclipse?
This bundle is an all-in-one solution for a small group. It provides two 50mm filters to equip a pair of binoculars for a magnified view of the eclipse phases, and 5 pairs of eclipse glasses for simultaneous naked-eye viewing. Both the filters and glasses meet the ISO 12312-2 safety standard, ensuring everyone can watch safely.
I have 10x50 binoculars. Will these 50mm filters allow me to see sunspots?
Yes, as long as the front barrels of your 10x50 binoculars measure 50mm to 69mm in outside diameter. The 10x magnification will be more than enough to resolve large sunspot groups on the solar surface clearly and safely.
Can I use one of these 50mm filters on my 200mm telephoto camera lens for photography?
Yes, as long as the front of your camera lens measures between 50mm and 69mm in outside diameter. The foldable design allows it to create a cap over the front of the lens. You can then safely use your camera to photograph the Sun.
