The 86mm North Star Filter from Tiffen creates multiple points of light, or "stars," streaking outward from a central light source. This filter comes in a rotating mount for critical placement of the star effect.
This filter is especially useful for wedding photographers. It helps create a romantic, special effect mood which clients desire. North Stars are best used with a point light source such as a candle, match, flashlight or streetlight.
Tiffen's ColorCore glass is produced through a process that entails permanently laminating the filter material in between two pieces of optical glass that are ground flat to tolerances of a ten-thousandth of an inch, then mounting them in precision aluminum rings.
How would this filter behave when shooting a sunrise?

While it will depend on the size of the sun in your image (and to some extent, your chosen aperture and focal length), it should behave similar to the sample image on our website. The main difference is, as the sun is both a large and bright light source, the points in the star would be much wider than when photographing a smaller light source or a small specular highlight. The size of the bands would typically depend on the size of the sun in the image. As focal length plays a part in the size of the sun (as well as the sun's position in the sky and/or as it approaches the horizon), wide angle lenses may typically have thinner points, while telephoto lenses would have wider points.
