Just running an experiment, it’s not that I actually want diffraction spikes, it’s just that was curious on how to make them without having the programs usually used, I downloaded several iOS apps but they basically turn every point of light in to a starburst so I just tried a old composite method, just found a diffracted star from hubble and overlaid it on 5 of the brightest stars in my lagoon photo, I suppose some photos may benefit, I’ve seen some photos of the plaides that I think are more beautiful with the artifact

You could cross two thin sticks or two strands of fishing line in front of your refractor, too...looks much more real. Because it is :)

Yeah I could but I won’t, I’m pretty fine without, just wanted to learn, but in this case of compositing, they are real, just from a different star and different scope :)
