Filter Optolong IR Pass 685 nm 2"
The Optolong IR-Pass filter is particularly suitable for planetary photography, as it eliminates the shortest wavelengths, obtaining a stabilizing effect on the image, greatly reducing the defects introduced by atmospheric turbulence.

Filter Optolong IR Pass 685 nm 2"
The IR-Pass filter of Optolong blocks wavelengths below 685 nanometers. At wavelengths above this value (in the infrared band), planetary images are less disturbed by atmospheric turbulence and better seeing is obtained. By combining a luminance image obtained with this filter and RGB, the increase in detail is significantly enhanced. With this technique, images of Venus and Mars become spectacular.
The ultra-thin filter cell minimizes vignetting by allowing a diaphanous aperture of 45 mm for 2" (50.8 mm), having been manufactured in aluminum by CNC machines with extreme manufacturing precision.
