Hi guys. I got sent this file to print for my Rasa 8. This will give me diffraction spikes in my images,which I really want. But I'm just not sure if the measurements are right? And if so what's the best option. The FDM or SLS? Thanks in advance

Hi 
just wondering if would be easier to add the diffraction spikes in post processing. If you have PS, there is an action tool from Noel Carboni. You can even select if you want to add the spikes to bright or small stars

I will never understand who wants spikes in telescopes that don't suffer of this artefact.
…we used to build curved vanes for newtonians in order to avoid spikes and obtain "refractor like" images! smile
of course tastes are personal smile

I'ld use a design that also leads the wires to the camera in front of the RASA - they make diffraction spikes anyway. And if you attach them to this with cable binder, you'll get strange spikes.
