Universal
Dark-Sky Filter with
77mm thread for photo lens. Contrast enhancing filter for
Aurora- and Deep-Sky imaging.
Especially during
Aurora imaging the most important wavelength of
550nm (green) and 630nm (red) this filter let pass by 90%.
In comparrision to CLS filters, the
Explore Scientific Dark-Sky Filter is blocking also the
yellow Sodium (Na) wave at 590nm which
elliminates Sodium-lamp street illumination from your picture.
This is very useful because the
yellow light is always a partially mix of green and red light. Removing the yellow wave-length with any image processing software will always damping also the green and red coloring. For Aurory imaging this is of course not wanted.
At these days of increasing
light pollution, the
Explore Scientific Dark-Sky Filter is
absolutely recommended in order to take pictures also from urban conditions.
Finally the
slim housing design enables its use also with
wide-field photo lens and doesn´t cause any vignetting.
