The Ԑ-130 and Ԑ-160 were pioneering Astro cameras. They used a hyperbolic primary mirror and a four element corrector to produce flat field high contrast photographic images using film.
The new digital corrector uses two elements in two groups to provide. This new design features superior correction from the original design and distortion has been reduced by 50%. The corrector is totally compatible with the new digital cameras. The corrector produces a flat Ø40mm image circle with 15 micron stars across the field. The multi-coatings, reduction in lens elements produce a very high contrast image.
Switching out the corrector is simple since the new design is the same mechanically as the original. Remove the original, and replace it with the new corrector.
