circular polarizer CPL telescope filter, High transmittance optical glass, Compatible with 1.25 telescope eyepiece, astrophotography camera,Astronomical Observation Components
Polarizers provide color and contrast enhancement Standard thread interface, suitable for 1.25 inch telescope eyepieces and astronomy cameras. Reflected light often shows up as whitish glare that washes out color in an image,Polarizer corrects this problem producing deep, dramatically blue skies. Eliminating lunar glow to make targets clearer and depth of field stronger. Enhance the contrast of images captured by telescopes. Filter Production Process Precision polishing of optical lenses, with good parallelism and surface accuracy, can effectively eliminate halos. Single piece circular polarizer, easy to use. Good film density, using ion plating technology. High quality aluminum alloy material frame, black oxidation extinction treatment to prevent reflection. Connect other functional filters in series to achieve the superposition of multiple filter functions. CPL Filter Parameters Model:Dawn02 Glass material: High pass transparent glass, multi-layer coating Interface:M28.5X0.6mm Size:31.75LX31.75WX8H mm Weight:5g Surface :H Grade:A Precautions for Use Filter increases nebula contrast, not brightness Keep lenses clean and prevent wear and tear
