Details

Introducing the Explore Scientific Dark-Sky Filter 77mm Slim - a universal Dark-Sky Filter with 77mm thread for photo graphic lenses. This filter will effectively boost contrast and create a more naturalistic sky background for wide field imaging - with the added bonus of less image processing afterwards.

During Aurora imaging this filter lets 90% of the most important wavelengths of 550nm (green) and 630nm (red) through to your camera. In comparrision to CLS filters, the Explore Scientific Dark-Sky Filter also blocks the yellow Sodium (Na) wave at 590nm, which elliminates Sodium-lamp street illumination from your pictures.

This is very useful because the yellow light is always a partial mix of green and red light. Removing the yellow wave-length with any image processing software will always lead to the reduction of both the green and red parts of the spectrum too. This is naturally particularly unsuitable for Aurora imaging. Subsequently, if you're planning an expedition to observe and photograph the Aurora, this filter should be top of your list of accessories to pack!

At these days of increasing light pollution, the Explore Scientific Dark-Sky Filter is very much recommended for wider field astrophotography from urban and suburban locations.

The slim housing design enables its use also with wide-field photo lens, which will avoid any possible vignetting.
