For many of these pics I had the lasers pointed straight down into prisms to try to get a nice symmetry of vertical lines. The first few have are using a Laserbtb diffraction star cap. On others I added my 589nm thru a fan diffraction grating into a mirror to add to shots. And the pics at the end of the post were angling the lasers to shoot into the prisms at a bit of an angle. I think there are a few nice ones. Enjoy.
