A note on choosing a solar filter:
Each Astrozap solar filter size listing represents the outside diameter of the telescope's OTA or dew shield that the filter is designed to cover. We suggest that you measure the diameter of the objective end or dew shield of your OTA in millimeters and select a filter in a size large enough to cover the objective completely. For binoculars, measure the outside of both objective lenses Do not wait until the week of the event to confirm that your solar filter fits your telescope or binoculars, and can be secured in its place in front of your telescope's objective or binocular lenses. Once you receive your order, immediately check and verify that the filter is undamaged, that it fits over the objective(s) completely, and that the adjustment screws tighten enough to hold the filter in place. You must confirm this before attempting to point your telescope or binoculars at the sun in order to ensure that the filter protects your eyes and your equipment. If the filter does not completely cover the objective(s), or is loose and does not stay firmly in place, or if it shows signs of damage, do not use the filter or point your optical equipment at the sun. Ever. Notify Astrozap to obtain a replacement (but if you wait too long, Astrozap cannot guarantee that you will receive a replacement before the event). Failure to verify the integrity, full coverage and secure fastening of your filter before each use will result in damaged optics and permanent injury to your eyes.
Neither Astrozap nor Mile High Astronomy are liable for damages to persons or property resulting from the user's failure to exercise ordinary care in the ordering, installation, and use of a solar filter.
