Color Correction
Showing: 1
SV231
  • Correct chromatic aberration; SV231 telescope filter prevents unwanted color banding in the blue spectral range; minimizes blue wavelengths in out-of-focus areas;
  • OD>4; the higher the filter cut-off depth; the smaller the noise and the higher the imaging contrast;
  • Full thread design; M48x0.75 specification; male thread; thread is not easy to wear; you can overlay other filter to use;
  • AR anti-reflection coating design; transmittance exceeds 95%; improves the contrast and clarity of fast achromatic telescopes, ensures image quality and brightness; obtains more observable light;
  • Good performance coating; telescope color correction filter has plasma-enhanced dielectric coatings result in hard; scratch-resistant and waterproof filters;
  • 300-1200/NM wavelength; blocking light damage and eliminating blue and purple streaks.
