- These filters will arrive in box that is foam-lined and then placed in plastic, perfect for storing the filter when you aren’t using it. It also comes with instructions for care and use, which when followed, will provide many years of enjoyment and use.
- The material for the optical thin film is created from .002” black plastic polymer to provide years of use. These premium solar filters are made with an aluminum cell that has been centered and is securely fastened to binocular ends with a nylon thumb screw and a piece of felt for padding.
- 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.
