DESCRIPTION
The Baader Fringe-Killer filter is a high-quality optical tool to reduce chromatic aberration in achromatic refractors. It blocks defocused light in the deep blue and above 700 nm in the infrared, effectively reducing purple fringing without altering overall image color.
This filter significantly improves image sharpness and detail, especially on the Moon and planets. It features precision polishing and is usable before focus, making it compatible with afocal photography setups. The dielectric hard-coated layers are plasma-deposited for maximum durability and optical clarity. An ideal upgrade for budget telescopes.
