Solar filter for 70-90mm tubes

The iOptron White Light Solarlite Solar Filter is designed for telescope tubes from 70mm to 90mm in diameter. It provides a 60mm clear aperture for detailed white-light solar observation. The filter uses Solarlite film to reduce solar intensity for safe viewing of sunspots and granulation. Its 4.10 inch inner diameter ensures a secure fit on compatible optical tubes.

For owners of small refractors or reflectors

This filter suits astronomers using telescopes with tube diameters of 70, 76, 80, 85 or 90mm who want to observe the sun in white light. It is not for observers whose telescope tubes fall outside this specific size range. Buyers needing a larger aperture for bigger instruments cannot use this model. It is also unsuitable for hydrogen-alpha or calcium-K solar observation.

60mm aperture with 99.999% light reduction

The decisive specification is the 60mm clear aperture paired with Solarlite film that filters out 99.999% of sunlight. This combination determines the resolution of solar details visible and the safety level for both eyes and equipment. The 4.10 inch (104.14mm) inner diameter confirms mechanical compatibility with the listed tube sizes.
