The bigger clear aperture brings wider field of view in guiding. It is easy to use, and suitable for users who are interested in long focal length photography. To take the most advantage of it, we recommend you to match it with large format guiding cameras.\u003c\/p\u003e\n\u003ca href=\"https:\/\/astronomy-imaging-camera.com\/wp-content\/uploads\/0121.jpg\"\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/2e3bbca6e1c2e115d30866b8e6e32051.webp?v=1752851312\" alt=\"\"\u003e\u003c\/div\u003e\n\u003c\/a\u003e\u003ca href=\"https:\/\/astronomy-imaging-camera.com\/wp-content\/uploads\/0321.jpg\"\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/a\u003e\n\u003ch4\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003eLightweight and exquisite, 17.5mm thickness.\u003c\/li\u003e\n\u003cli\u003ePrism size: 12*12mm.\u003c\/li\u003e\n\u003cli\u003eThe effective light-passing aperture is 11.7mm*8.3mm.\u003c\/li\u003e\n\u003cli\u003eCan be used to connect the main camera and guide camera simultaneously.
