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: 25% ND16: 12.5% ND32: 6.25%
.

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.
