It is quite difficult to get a primary mirror mask / aperture ring for a 12" Newtonian (300 mm).
That's why I designed a multi-part mirror mask for my Skywatcher 300 PDS Newtonian. I cannot say whether it is also suitable for telescopes from other manufacturers.It's quite difficult to get a primary mirror mask / aperture Ring for a 12 "Newton(300 mm).
Part list
- 6 prints
- 6 nuts M3 hexagon nuts ISO 4032, you can try if square nuts are fitting
- 6 Screws M3 x 12 mm, ISO 4762 Socket head screw or ISO 7380 Hexagon socket button head screw
- anti-reflective paint black
Printing
Nozzle 0.4 mm, material doesn't matter (I printed in PLA), no support, no brim. Infill around 10%, not for stability reason but the internal overhang wall needs infill as support (see pic OrcaSlicer).
Painting / adhesive foil
Painting with black anti-reflective paint or even better cover the top and bottom with an adhesive foil made of black velour velvet fabric.
