SV199 1.25'' ADC Atmospheric Dispersion Corrector

• The main function of ADC is to reduce the color change caused by atmospheric dispersion and improve the imaging effect of planets; especially low-altitude planets
• A pair of prism lenses adopts double-sided coating process to reduce light loss; coating adopts anti-reflective broad-band; applicable range from 300nm to 700nm
• Camera and eyepiece side 1.25 inches barrel with T2 male thread; adaption is simple through T2 thread and 1.25 inches barrel on camera side and 1.25 inches barrel on telescope side
• Through the use of 2 quality minimum 1/4λ BK7 prisms; it corrects the false colour introduced by the earth´s atmosphere；double wedge prism with 4.5 degree declination adjustment range
• The ADC corrects the dispersion effects of earth´s atmosphere; you will get sharper images of planets and moon; when used for planetary imaging; it changes the clarity of the image dramatically; particularly in the luminance channel when LRGB imaging
• Ring scale for adjusting dispersion correction; less fringing; clearer planet photos and more details; the eyepiece or camera installation interface adopts coaxial locking interface ensures sufficient coaxiality
• FMC prism lens; prism lenses employ a double-sided coating process to reduce light loss make sure the light transmission of the ADC is high
