Dark sky filter with77mm filter thread for photographic lenses: Particularly well designed to increase contrast duringaurora- anddeep sky photography!

In nature and macro photography, red and brown tones (e.g. dawn colours, sunsets, autumn foliage) are accentuated and better differentiated.

• Reducing light pollution from streetlights, etc.
• Blocks yellow light - a clear advantage which cannot be applied retrospectively during post-production on the PC.
• Made from special optical glass with neodymium oxide

Ideal forwide-angle images of the Milky Wayand the night sky using photographic lenses: Unlike well-known interference filters (CLS, UHC), these filters can be placed on the front of wide-angle lenses. Interference filters require perpendicular light and, therefore, need to be mounted between the lens and the camera for wide-angle images.
