Spectrum 3.75″ Full Aperture Film Solar Filter – 86mm to 92mm

These premium full aperture Thin Film Solar Filters allow only a safe amount of light to pass through your telescope, camera, and binoculars for solar viewing. It is an ND 5 filter, therefore blocking 99.999% of the Sun’s visible light. The .002″ thick black plastic polymer used for the filter substrate is a durable, high quality material that will last you for many years with proper care and handling. These filters are constructed with a single-layer design with absorptive filtering material spread throughout the substrate. Slight warps, bends, or wrinkles present in the film will NOT affect the solar image. The Sun appears in a natural looking yellowish-orange color that we are all familiar with, rather than harsh white-light.

This filter fits: Celestron FirstScope: 60 AZ & EQ, 80 EQ ; Meade: ETX-60AT, ETX-70AT, NG-60 (with dew shield) ; Orion: Observer 60 Alt-Az and EQ ; Tele Vue, Tele Vue Pronto ; Vixen: A80Mf, A80SSWT, ED81SWT.
