This adjustable white light solar filter from iOptron uses SolarLite film to provide you the best possible optical clarity for a film solar filter. The 70mm adjustable solar filter is comparable to an equivalent size glass filter in quality, but is a fraction of the price. It provides a natural yellow-orange image of the sun to you when used with a fitting telescope, and is easy to attach and remove as needed. This filter fits most 70mm to 90mm telescope tubes, as well as some camera lenses. It has an inner diameter that ranges from 84mm to 106mm and clear aperture of 70mm.
Safety Note: Please never remove the filter while in use, or look at the sun without the filter slotted into your telescope. You must firmly and completely attach the filter, and we strongly recommend checking the tightness as well.
