How do I find the right size filter to order?
When ordering telescope, spotting scope, binocular or camera filters you need to know the outside diameter of your optical tube. For a correct fit, measure the widest distance across the end of your optical tube from outside edge to outside edge.
What is the difference between Glass and Thin Film Solar Filters?
Glass solar filters have an aperture made of highly reflective metal coated glass. The glass filters demonstrate a higher resolution than thin film which is why they are recommended for photography. For viewing the comparison is personal preference.
Are the Solar Filters safe?
Yes. All of our Glass and Thin Film Solar Filters are safe for unlimited visual use and photography. Helios Solar Film and Helios Solar Glass® have been tested and meet the requirements for ISO 12312-2.
These filters block 99.999% of the sunlight and therefore are rated with a neutral density of 5. Careful handling and proper maintenance will ensure a long filter life.
What should I expect to see?
With your optical device you will see sunspots, solar granulation (suns Photosphere), transits, or a solar eclipse.
Can the telescope optics get hot or damaged?
The heat and intense light is blocked before it enters the telescope. Your telescope may get warm from direct sunlight on the telescope but not from the small amount of visible light transmitted through the filter. Please read and understand your filter instructions before use.
What is thin film?
There are many “thin films” on the market today used for solar viewing. Some of them include Mylar, Baader, and Black Polymer. The thin film we use in our filters is Black Polymer which has a neutral density (ND) of 5 and is safe for solar viewing . The sun is viewed as a sharp natural orange image, not blue or white.
What is the difference between a full aperture and off axis solar filter?
An off axis solar filter blocks light into the telescope by only allowing light through a small portion of glass that is off center. A full aperture filter allows the most light into the telescope because it allows the full aperture of your telescope to be viewed. This allows the best possible daytime viewing when there is minimal atmospheric turbulence. If turbulence is present, a mask can be put over the end of the filter to effectively reduce the aperture. With a mask you can effectively change the aperture range to anything less than full aperture depending on the size of the mask. An off axis solar filter cannot be used on a refracting telescope.
