The telescope used is SkyRover 102 APO Pro. As we can see the focus positions after each auto-focus are very close, with the minimum position being 39582 and the maximum position being 39593. On the SkyRover 102 APO, the moving distance of each motor step is 0.8μm. So the maximum position deviation between each of the 12 consecutive auto-focus is less than 9μm. All the hyperbolic fitting coefficient of determination (R2) are above 0.99, indicating that the focusing results have high stability and accuracy.\u003c\/span\u003e\u003c\/p\u003e\u003cp style=\"text-align:center\" align=\"center\"\u003e\u003cimg width=\"400\" height=\"7837\" src=\"https:\/\/ae01.alicdn.com\/kf\/S2469ccdf242d4cee81f552d02f80705cd.jpg\" slate-data-type=\"image\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e\u003cspan style=\"font-size:16px\"\u003ePlease note:\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e\u003cspan style=\"font-size:16px\"\u003eMany factors may impact the auto-focus result, such as wind, seeing, and the auto-focus parameter settings etc. In order to get good auto-focus results like the ones shown above, we need to do many things right. \u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003ch1\u003e\u003cspan style=\"font-size:20px\"\u003e\u003cstrong\u003eContact us：\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h1\u003e\u003cp\u003e\u003cspan style=\"font-size:16px\"\u003eEmail：support@astroasis.com\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size:16px\"\u003eWebsite：https:\/\/www.astroasis.com\/en\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size:16px\"\u003eFacebook：https:\/\/www.facebook.com\/astroasis.space\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size:16px\"\u003eYouTube：https:\/\/www.astroasis.com\/en\/\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Astroasis Store","offers":[{"title":"ROSE-ASQA55","offer_id":43021710852186,"sku":"14:175#ROSE-ASQA55","price":352.77,"currency_code":"USD","in_stock":false},{"title":"ROSE-C30-ALCN","offer_id":43021710884954,"sku":"14:200002130#ROSE-C30-ALCN","price":363.55,"currency_code":"USD","in_stock":false},{"title":"ROSE-AACL200","offer_id":43021710917722,"sku":"14:350850#ROSE-AACL200","price":411.64,"currency_code":"USD","in_stock":false},{"title":"ROSE-ARC51","offer_id":43021710950490,"sku":"14:691#ROSE-ARC51","price":411.64,"currency_code":"USD","in_stock":false},{"title":"ROSE-C30-A20472","offer_id":43021710983258,"sku":"14:771#ROSE-C30-A20472","price":363.55,"currency_code":"USD","in_stock":false},{"title":"ROSE-C28-ASND","offer_id":43021711016026,"sku":"14:193#ROSE-C28-ASND","price":363.55,"currency_code":"USD","in_stock":false},{"title":"ROSE-C30-A20473","offer_id":43021711048794,"sku":"14:365458#ROSE-C30-A20473","price":363.55,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0712\/9209\/2506\/files\/S3ce869d3b79545239fd50766614d338br.webp?v=1773130043","url":"https:\/\/store.astroasis.com\/products\/oasis-focuser-rose-installation-with-dedicated-adapters","provider":"Astroasis Store","version":"1.0","type":"link"}
