The AAF (Astro Automatic Focuser) replaces the focus button on your focus ring with a stepper motor. Through the software, you can set the focus automatically, even in the middle of the night when the temperature drops and the brandpoint shifts. The temperature sensor helps with this.<\/p>\n
The motor fits most telescopes; it comes with several connecting pieces and a horizontal and vertical mounting plate. You connect it via USB-C and it works with ASCOM and INDI drivers, so with N.I.N.A., StellaVita and other programs. With the included hand control, you can also focus without a computer.<\/p>\n
Hello<\/strong> who makes long sessions and doesn't want to adjust them manually all the time.<\/p>\n Not<\/strong> who only looks at it visually.<\/p>\n Focus motor that you attach to the focus ring of your telescope or guide telescope. Automatic focusing via software, with temperature sensor and manual control.<\/p>","protected":false},"featured_media":114497,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[3365],"product_cat":[469,3114,3104,56],"product_tag":[],"class_list":["post-114501","product","type-product","status-publish","has-post-thumbnail","product_brand-touptek","product_cat-astro-fotografie","product_cat-electronic-focusers","product_cat-overige-astrofotografie-accessoires","product_cat-telescoop-accessoires","first","instock","taxable","shipping-taxable","purchasable","product-type-simple"],"bundled_by":[],"bundle_stock_status":"instock","bundle_stock_quantity":null,"bundle_virtual":false,"bundle_layout":"","bundle_add_to_cart_form_location":"","bundle_editable_in_cart":false,"bundle_sold_individually_context":"","bundle_item_grouping":"","bundle_min_size":"","bundle_max_size":"","bundle_price":[],"bundled_items":[],"bundle_sell_ids":[],"acf":[],"jetpack_sharing_enabled":true,"jetpack-related-posts":[{"id":114496,"url":"https:\/\/www.telescoop.nl\/en\/touptek-stellavita-wifi-controller-voor-astrofotografie\/","url_meta":{"origin":114501,"position":0},"title":"ToupTek StellaVita wifi controller for astrophotography","author":"Info telescoop","date":"22-10-2026","format":false,"excerpt":"A mount for your telescope that controls the camera, the mount, the focus motor and the filter wheel via Wi-Fi.
