I was not happy with the star shapes I got from the commonly used semicircular cable router so I designed this. It incorporates an aperture mask of 198mm and 4 cable routing channels that give stars a typical newtonian diffraction pattern.

After printing use a few wraps of tape around to circumference to give a snug fit. It should engage the two pins inside the front aperture ring. After sliding it in rotate 5 degrees clockwise to lock it in place.

There are 3 versions:

• 3mm wide cable channels for RASA 8
• 6mm wide cable channels for RASA 8
• 3mm wide cable channels for C8 w/Hyperstar
