iOptron 70mm White-Light Solar Filter
Key Features
  • Adapt Nighttime Scope for Solar Viewing
  • Optical Density of 5
  • 70mm Clear Aperture
  • Fits Most 70-90mm OTAs
Designed for use on your 70-90mm aperture nighttime optical tube assembly for viewing the sun or solar eclipses, the iOptron 70mm White-Light Solar Filter fits over the front of the OTA's dew shield and is held in place with three thumbscrews. For longevity and safety the filter is made of an infused polymer material called SolarLite to ensure that it will not develop pinholes or scratches — and since it's rigid, it won't tear or puncture like film filters can. It has an optical density of 5 that transmits just 1/1000th of 1% of the harmful intense light from the sun to make it safe to view.

SAFETY FIRST: Observing the Sun without the proper protection may result in serious personal injury, including permanent eye damage and blindness, and/or damage to equipment. Never point an optic at the sun without an approved solar filter on the front of the optic. For direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder, ensure your filter is ISO 12312-2 (also written as ISO 12312-2:2015) certified. Never use photographic neutral density filters for direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder.

iOptron TSF70 Overview

Designed for use on your 70-90mm aperture nighttime optical tube assembly for viewing the sun or solar eclipses, the iOptron 70mm White-Light Solar Filter fits over the front of the OTA's dew shield and is held in place with three thumbscrews. For longevity and safety the filter is made of an infused polymer material called SolarLite to ensure that it will not develop pinholes or scratches — and since it's rigid, it won't tear or puncture like film filters can. It has an optical density of 5 that transmits just 1/1000th of 1% of the harmful intense light from the sun to make it safe to view.

To ensure the filter will fit your OTA, simply measure the outside diameter of the dew shield — the filter's mounting ring has an inside diameter from 84-106mm so as long as the outside diameter of the dew shield falls in that range, it will fit. Remember to practice safe solar viewing techniques and never look directly at the sun without certified solar viewing glasses and equipment.
