Stars that are normally comet-shaped distortions appear as sharp, point-shaped stars thanks to this corrector - ideal for wide-angle astrophotography and sensors up to full-frame size.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In addition to field correction, the corrector shortens the focal length by a factor of 0.85. This produces a brighter image and reduces the exposure time required, allowing you to capture more detail in shorter sessions. The optics consist of a carefully designed quadruplet lens system with full multicoating for maximum transmission and contrast.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The corrector has an exposure diameter of 44 mm, making it suitable for full-frame cameras. The back focus is 55 mm, which matches most DSLRs and astro cameras in combination with a T-ring or adapter. Multiple threaded connections are provided for maximum flexibility: M76 \u00d7 1 (external), M68 \u00d7 1 (internal) and M54 \u00d7 0.75 (internal).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Application<\/strong><br>Suitable for Newton telescopes with an aperture ratio of f\/3 to f\/6 and a 3\u2033 focuser.
