Wanderer ND Filter for V4-EC/V4-EC-IR Wanderer Cover - 80 mm - WC4ND-80

The ND filter assembly for the 80mm WandererCover is designed specifically for users with fast optics who insist on taking long-exposure flats. It extends exposure time by around 32 times. However, in most cases, you DO NOT NEED it — WandererCover is designed to be flicker-free, ensuring clean, banding-free flats even at very short exposures.
