Building artificial star
My C8 OTA needs a collimation process to be completed. I have seen some artificial stars usually made my pinching a small hole to a very thin metal foil.
I wanted to build a "prototype" of a artificial star, which had very small hole for light rays. I had some pieces of broken single mode fibre, which should be fine.
Both ends had a exposed connector (SC type if I correctly remember). Cable type designation was 10/125 - which means very thin core of optic cable. I put my small Maglite into other end of cable. With the beamwidth, I could adjust brightness of a artificial star.
I did not put all the things in enclosure. If have some extra time, maybe then...
