Why Clip Filter?
^Due to the differences in optical design among various lenses, when used with some fish-eye lens, ultra wide and wide angle lenses, the corners of the image might appear softer which is a normal optical phenomenon

Placing the light pollution filter closer to the sensor reduces color shift that may occur at the peripheral areas of the image if front screw-in lens filter is used. STC recommends using STC Astro Duo-Narrowband Clip Filter for Nikon-APS-C with SLR lenses of focal length 14mm or longer, and avoiding directly taking pictures to strong artificial light which may cause slight flare on image.
Installation Procedure
A. Remove the lens from the camera.
B. Insert the Astro-MS clip filter into the camera.

STC Technologies

STC utilises ion beam assisted deposition (IBAD) to solidly bind the coatings onto Schott B270 glass, the very same glass used in Zeiss lenses. Such technique enhances the light transmission and also durability of the 160 layers of coating deposited to produce the advanced filter characteristics shown above.
With patented Ultra Layer® technology, both surfaces of Astro-Multispectra are coated with Anti-Smudge nano-coating to prevent dust and water from settling on the filter surface. Dew will not form and your filter is always clean. If necessary, it's effortless to clean.
