Optimize your astrophotos and completely eliminate camera noise and "hot pixels" with this opaque filter. It blocks all light from your camera's imaging sensor, making dark frame acquisition easy.
Pesky camera noise can ruin astrophotos by leaving distracting bright spots and unwanted fixed patterns on your captured exposures. Dark frame acquisition helps remedy such noise and "hot pixels" by canceling out these disruptive effects during image processing. This handy filter ensures your acquired dark frames will be completely free of unwanted stray light and reflections for great results.
