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.
