Details

A Schmidt-Cassegrain Telescope will show substantial image errors (most prominent being coma and image field curvature errors). ASA Astrosysteme is now offering a new SC Reducer Corrector, which was developed by Dipl. Phys. Philipp Keller and is built by ASA. The corrector not only reduces the outer axial image errors but is also able to correct chromatical aberration errors which are introduced by the Schmidt plate. The results are pinpoint stars not only to the side but also into the image middle. The reducer will correct the focal length down by a factor of 0,77x. It is perfectly suitable for perfect image performance onto APS-C format sized CCD chips.
