easy-spike M58

Telescopes with secondary mirrors produce spikes. This looks beautiful and also illustrates the difference in star colours better than an almost point-shaped star image.

If you take photos with a normal camera lens, you have to do without these spikes. With "easy-spike", however, these diffraction patterns can now be easily achieved on a camera lens without any tinkering or post-processing on the computer. The masks are available in almost all common sizes.
