During my last visit in the Provence for theATOS-project I visited my good friends Caroline and Jean-Luc Plouvier from the Domaine de la Blaque in Varages. You should visit them. It's paradise.
Was able to use Jean-Luc's Mesu 200 mount to make some astrophotos with the Zeiss Jena 1000mm f5.6 Spiegelobjektiv.
M13 in Hercules, Zeiss Jena 1000mm f/5.6 Spiegelobjektiv
The 1000 Spiegelobjektiv (mirror lens) was manufactured always in a Pentacon Six mount with appropriate35mm mount adaptor included ( M42, Exakta, & Praktina ).
This is one of the mythical lenses made by Carl Zeiss Jena with a fantastic finishing. Mechanical and optical a masterpiece.
Tested the Spiegelobjektiv with a Sony Alpha 7S and it's an excellent lens. Also for astrophotography
