TS Optics secondary mirror holder for mirrors from 50 mm minor axis upwards:
The secondary mirror holder is completely made of metal. The weight was reduced to only 77 g by clever design – with maximum stability.
The secondary mirror is glued to the plane surface. A double-sided tape is included, but we recommend the use of silicone.
A slight offset is already regarded by the holder. If you glue the secondary exactly centrically on the holder, the offset is correctly preset for a focal ratio of f/5
