The RB-Focus Aperture Ring for Reflecting Telescopes fixes a common misconception of most mirror cell telescopes, the helix-shaped reflections that form on stars other than diffraction spikes, if you've wondered where These strange reflections come from the clips that hold the mirror to the cell. An opening ring allows the clips to be covered to completely solve this problem. It is very simple to install and is currently available for telescopes with 150mm aperture and up.

- 8" aperture ringMar 24, 2024Rated 5 out of 5 stars.Just right
I got this with my focuser base and it's exactly the right size to cover the primary mirror holding clamps. I was getting odd-shaped diffraction spikes (I know, it's normal) and already knew to change the focuser and add an aperture ring. This fits perfectly. Thanks RB Focus.

El sistema de fijado que trae, almohadillas adhesivas de dos caras, con el tiempo y cambios de temperatura acaba cediendo y se suelta. Estaría mejor que estubiese perforado para poder utilizar los tornillos que sujetan el espejo primario para sujetar también el anillo, pero debería ser un poco más grueso para evitar deformaciones.
