The helical mechanism provides 6 mm of travel with a 0.1 mm fine adjustment, and the attached accessory does not rotate during focusing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This non-rotating design is essential for guides and sensors: the orientation is maintained while you refine the focus. A locking screw secures the found position, so nothing shifts during the session.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Features<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li>6 mm slag met 0.1 mm fijninstelling<\/li>\n\n\n<li>Non-rotating: orientation of camera or prism is maintained<\/li>\n\n\n<li>The clamping screw secures the focus position<\/li>\n\n\n<li>Compact enough for OAG guide ports<\/li>\n\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Compatibility<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Telescope side: female T2 (M42 x 0.75).
