With this reduction of the aperture, the image doesn’t become darker but instead, daytime visibility of atmospheric turbulence is minimized. This style is less expensive than a full aperture solar filter.There is an aluminum cell with this premium solar filter which has been centered and secured to the telescope’s end with felt padding and nylon thumb screws. For best results, the position of the filter should be as near the 12 o’clock position as possible.

This box can also be used for storing your filter when you aren’t using it and there are thorough instructions on how to care and use the filter. How do I determine the size of filter to order? Spectrum Telescope filters slip over the sky end of the optical tube of the telescope. To get the proper fit, measure the outer diameter by using a caliper, ruler, or tape measure. Measure the widest distance of the telescope end starting from the exterior of the casing, across the center and to the exterior part of the casing of the other side. After you have your measurements, you should order a size larger than what you measured. This is because your measurement is being compared with the solar filter ID (inside diameter). For instance: If you measure 4″ across the optical tube end needs a 4.25” size solar filter. This will make it just a little bigger than the measurement you took. Are the glass and thin film solar filters safe?Yes, all of our filters are safe, blocking up to 99.99% of the sun’s rays, perfect for unlimited visual use as well as photography. These filters are rated with a neutral density of 5. With proper care and handling, our filters will last for many years.
