I received the 0.4-m primary mirror back from Orion Optics without any charge. This is very professional of Orion Optics to help me with this problem. I tested the mirror with Foucault an ronchi and now the mirror looks very good an correspondiong with the report of OO. I put the mirror again in the telescope, do collimation with Cats-eye tools and placed the telescope on the ASA DDM85 mount. After en evening of polaralignment en calibration, i could start with first light ! The images looks very promising, stars are much better, only i see some pinned optics and the distance of CCD to the corrector isn’ very accurate – i see on the edges some coma. In the center OK.
