1.25inch O-III Filter greatly enhances contrast during visual observation of gaseous and planetary nebulae in all sky conditions; astrophotographic 1.25inch filter allows high-contrast imaging even in areas with strong light pollution
Especially useful for large aperture telescopes through which the light of the Moon can be extremely overwhelming; allowing just for the Double Ionized Oxygen lines between 496nm to 501nm to pass through at 95 percent
Completely blocks virtually all other visible wavelengths of light so views of nebulas are optimized; increases contrast through selective filtration-Anti-reflection coated to prevent glaring and ghosting
The new astromania off axis guider is the lowest profile off axis guider that we know; despite this no compromise has been made with the function and operating comfort of this versatile off axis guider; mechanical flexure between main and guiding telescope can possibly ruin the tracking accuracy if you use an off axis guider
1: Only off axis guider that can be used between coma corrector or field flattener and dslr camera no leaving tolerance distance between camera and corrector 6: Off axis guider provide space for filter wheel or filter drawer when using cooled ccd camera
