What is a starry sky?
Probably one of the most beautiful lighting effects which can be created that can be very simple or rather sophisticated. In its simplest form, a starry sky consequence is made with a number of little diameter fibers coupled to a huge solid core, that delivers the light from the illuminator. It creates a number of static points of similar diameter that can be quite effective when a little flat.
More elaborate systems use some fiber calibres', 0,25mm to 3mm diameter and run directly to the illuminator. The numerous sizes of fiber make for various intensities on the point light, providing the effect of distance and perspective creating great depth. Coupled along with a twinkle effect wheel the effect can be rather stunning.
