Diffraction spikes can be minimized or maximized based on your central obstructions of your telescope.  With a RASA design, there is inevitably cables that need to be guided out over your telescope, so here are a couple options to either maximize or minimize those diffraction effects.

With a complete 90 degree routing, you will get the natural bright effect similar to epsilon and other telescopes.  With a curved cable guide, you will minimize (not eliminate) those effects to the point where it will become only noticeable on exceptionally bright star targets.

It’s fun to experiment with, and you can download the STL files for free if you wish to print these yourself.

Max Diffraction Spike Generator

This version clips to the outside ring of your RASA 11 and has pin holes for the 2 declination pins on your outside ring to perfectly align with RA/DEC axis every time.  It also has provisions to grab one of the Photon Cage supports to align your cage every time to RA/DEC.
