DV4. Riccardi Honders 305 mm f/3.8 – Astro-Physics

 System characteristics

The Astro-Physics design is a modification of the Riccardi-Honders. It features diffraction-limited performance over a huge 3-degree field, which is ideal for capturing large faint nebulae over a wide wavelength range. The design has essentially perfect color correction from 400 to 1000 nanometers (UV to IR), is fully corrected for all typical aberrations (spherical, coma, astigmatism, field curvature and distortion), as well as longitudinal and lateral chromatic aberration.
