A clip designed to hold a 225mm filter or bahtinov mask in front of the skywatcher 200/1000 tube (200PDS)
The design is made to hold the filter in front of the telescope (with and without its cover). It also clip on the backside of the telescope to store it during observations ;)
The bahtinov mask pictured is made with this generator from Satoru Takagi

With these parameters:
Focal=1000mm
Outer Diameter=225mm
Inner Diameter=55
Stem/Slit Width=1:1

You'll need three M3x12mm bolts to assemble this clip to the filter.
