Breng je een nieuwe, lager bouwende focuser op je telescoop aan, dan ligt het scherpstelpunt soms net buiten bereik. Deze focuserverhoging van 25,4 mm, circa 1 inch, van Starlight Instruments zet een 2 inch focuser verder van de tubus, zodat je weer scherp komt.<\/p>\n\n\n\n
De verhoging komt tussen de focuserbasis en de focuser en schuift het hele scherpstelbereik naar buiten op. Een inch extra is een gangbare stap bij het wisselen van focuser. Losse modellen vind je bij de focusers voor telescopen<\/a>.<\/p>\n\n\n\n Ook als oculairs niet scherp komen omdat de uittrekbuis al helemaal uitgeschoven staat, kan een verhoging helpen. Stel eerst scherp, meet hoeveel bereik je mist en kies de verhoging die daar net bij past. Ga niet hoger dan nodig, want je verliest evenveel bereik naar binnen.<\/p>\n\n\n\n Mis je maar een paar millimeter, kijk dan naar de verhoging van circa 0,65 inch<\/a>. Is het verschil groter, dan is er de verhoging van 1,4 inch<\/a>.<\/p>","protected":false},"excerpt":{"rendered":" Riser van Starlight Instruments die een 2 inch focuser circa 1 inch hoger zet, handig na het wisselen naar een lager bouwende focuser.<\/p>","protected":false},"featured_media":113417,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[3291],"product_cat":[56,3091],"product_tag":[],"class_list":["post-113418","product","type-product","status-publish","has-post-thumbnail","product_brand-starlight-instruments","product_cat-telescoop-accessoires","product_cat-telescoop-onderdelen","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":32467,"url":"https:\/\/www.telescoop.nl\/en\/bresser-verlengstuk-35mm-2-inch\/","url_meta":{"origin":113418,"position":0},"title":"Bresser extension piece 35mm 2 inch","author":"","date":"02-11-2025","format":false,"excerpt":"Bresser verlenghuls 35 mm voor 2 inch focusers: lost focusproblemen op bij oculairs, binoviewers en camera's.
