Product Description
Spectrum Telescope’s Off Axis filters are designed for larger (> 8”) telescopes. The off axis design helps minimize the effect of daytime turbulence on the image. Made from the same materials as Full Aperture Filters these Off-Axis designs are more economical than full aperture filters.
