LP700 retains more deep red and near-infrared starlight signals, while balancing light pollution suppression and imaging signal-to-noise ratio.\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePackage Included:\u003c\/b\u003e\u003cbr\u003e- 1 x LP700 Filter for GPM Series\u003cbr\u003e- 1 x 6MM F1.2 CS Lens\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 750px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/106258\/106258-01.jpg\"\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"TeSeek Official","offers":[{"title":"Default Title","offer_id":68141329613036,"sku":"106258","price":25.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0755\/9669\/3740\/files\/20261110090824_f35b5690_37c5b9d3-d23d-493f-aaf0-38e262260e44.jpg?v=1794316264","url":"https:\/\/teseek.com\/products\/touptek-700nm-ir-filter-6mm-f1-2-cs-lens-astronomy-filter-accessory-kit-for-gpm-series-astronomy-cameras-1","provider":"TeSeek Official","version":"1.0","type":"link"}
