I just had my 18” Suchting primary recoated by Wayne a few weeks ago.
Aluminium coating with SiO2 and TiO2 IAD layers over the top for >96% reflectivity, Wayne also tested my Enhanced coating 4.5” secondary and it too was better than 96%.
Wayne’s laboratory premises are no longer available, I do hope that he decides to continue in 2020.
