The \u003cb\u003eBaader 1.25\" IR-Pass Filter\u003c\/b\u003e blocks wavelengths below 670 nm. At these longer wavelengths, planetary images are less disturbed by wavefront distortions in the atmosphere (seeing). By combining a luminance image taken with the IR-Pass filter, along with RGB frames, overall image sharpness is significantly enhanced. Some of the world's best amateur planetary images have been taken with this technique.\u003c\/p\u003e\n\u003cp\u003eThe \u003cb\u003eBaader IR-Pass Filter\u003c\/b\u003e shares the same outstanding features as all the other Baader filters. High optical quality, Striae-free substrate, and high efficiency multi-coatings result in the sharpest and highest contrast image possible.\u003c\/p\u003e\n\u003cp\u003e  \u003c\/p\u003e\n\u003ccenter\u003e\n\u003ch2\u003eBaader IR-Pass 670nm Filter Features...\u003c\/h2\u003e\n\u003c\/center\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe Baader IR-Pass Filter blocks wavelengths below 670nm.\n\u003cp\u003e \u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003ePlanetary images are less disturbed by wavefront distortions at these longer wavelengths.\n\u003cp\u003e \u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003eEach Baader Planetarium IR-Pass Filter substrate is fine-optically polished plane parallel for 1\/4 wavefront over entire surface.\n\u003cp\u003e  \u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003eMulti-layer dielectric coatings are plasma-assisted and ionbeam-hardened using the latest technology.\n\u003cp\u003e  \u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003eCoatings will never degrade from use or normal cleaning.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e  \u003c\/p\u003e\n\u003ccenter\u003e\n\u003ch2\u003eBaader IR-Pass 670nm Filter Specifications...\u003c\/h2\u003e\n\u003c\/center\u003e\n\u003cp\u003eFilter Type: Infrared Blocking\u003c\/p\u003e\n\u003cp\u003eFormat: Round, Mounted\u003c\/p\u003e\n\u003cp\u003eSize:  1.25\"\u003c\/p\u003e\n\u003cp\u003eThreaded: Yes\u003c\/p\u003e\n\u003cp\u003ePassband: 670nm\u003c\/p\u003e\n\u003cp\u003eCoatings: Dielectric\u003c\/p\u003e\n\u003cp\u003ePurpose: Photographic\u003c\/p\u003e","brand":"Baader Planetarium","offers":[{"title":"Default Title","offer_id":21761914945,"sku":"BAA-FIRP-1","price":84.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0851\/2766\/products\/2281-1-thumb.jpeg?v=1776459153","url":"https:\/\/khanscope.com\/en-fr\/products\/ir-pass-670nm-filter-1-25-round-mounted-firp-1","provider":"Khan Scope Centre","version":"1.0","type":"link"}
