Filters with 77mm filter thread for photo lenses : Particularly well suited for increasing contrast in aurora - and DeepSky photography !
In natural and macro photography, red and brown tones (e.g. twilight colors, sunset, autumn leaves) are emphasized and better differentiated.
- Reduction of stray light from street lights, for example
- Blocks the yellow light - a clear advantage that cannot be replaced by post-processing on the PC.
- Made of special optical glass with neodymium oxide
Ideal for wide-angle pictures of the Milky Way and the starry sky with photo lenses: In contrast to widely used interference filters (CLS, UHC), this filter can be used in front of a wide-angle lens, which is not possible with interference filters. Such filters require vertically incident light and therefore have to be mounted between the lens and camera in a complex manner for wide-angle shots.
