The 12 x 12 mm prism captures more than enough light for guide stars\u2014even outside a full-frame field of view\u2014and directs it to a Mini-guide camera. Guiding through the primary optics means tracking without flexure or differential errors.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The optical design is tailored to the ZWO system: OAG-L plus EFW filter wheel plus cooled camera results in exactly 55 mm of backfocus, the standard for most correctors. The included M48 tilt adapter squares the sensor for sharp stars right into the corners.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Features<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li>Large 12 x 12 mm prism for full-frame guiding<\/li>\n\n\n<li>Exact 55 mm backfocus with EFW and cooled ASI camera<\/li>\n\n\n<li>Included M48 tilt adapter for flat alignment<\/li>\n\n\n<li>No guidescope: less weight, no flexure<\/li>\n\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Compatibility<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Optimized for ZWO EFW filter wheels and full-frame ASI cameras such as the ASI6200 series.
