Feature

●Four neutral density filters with different light transmittances (T:25% T:12.5% T:6.25% T:3.125%) allow astrophotography enthusiasts to choose the appropriate lens for shooting according to the lightness and darkness of the target
●Aluminum alloy frame, with a high-transparency glass lens with optical processing
●Both sides M28.5x0.6 threads, which are easy to connect in series and realize the superposition of different filter functions
●Lunar Filter kit ND4 ND8 ND16 ND32, can be connected in series, packaged with environmentally friendly materials
●Choose wisely, and the universe will be your endless canvas


Description

Neutral Density Filter Cuts Glare,Enhance Contrast
Reduce moon glare, improve image contrast, highlight target details, create clearer images, and alleviate eye fatigue
Do not change the color of the target object, highlight the depth of field in the observed image
Standard thread interface, suitable for 1.25 inches telescope eyepieces and astronomy cameras
Transmittance:ND4: 25% ND8: 12.5% ND16: 6.25% ND32: 3.125%
.

Filter Production Process
HD optical lenses, with good parallelism and surface accuracy.
Screws into 1.25 eyepieces or astronomy cameras, easy to use.
High quality aluminum alloy material frame, black oxidation extinction treatment to prevent reflection.
Stacks connect other 1.25 filters to achieve the superposition of multiple filter functions.
