Kom je met je camera of oculair net niet scherp omdat je naar buiten tekortkomt, dan kun je de focuser verder van de tubus zetten. Deze focuserverhoging van 3,35 inch van Starlight Instruments plaats je tussen de focuserbasis en de focuser. Zo schuift het hele scherpstelbereik naar buiten, en dat is steviger dan een verlengbus in de uittrekbuis.<\/p>\n\n\n\n
Risers zijn er voor verschillende focusermaten, dus controleer voor je bestelt of deze aansluit op jouw focuser en focuserbasis. Bij een reflector van het type Newton<\/a> betekent een hoger geplaatste focuser bovendien dat de vangspiegel het beeldveld minder ver belicht.<\/p>\n\n\n\n Meet ook hoeveel extra bereik naar buiten je echt nodig hebt, want je verliest evenveel bereik naar binnen. Stel eerst scherp met je huidige opstelling en kijk hoe ver de uittrekbuis dan uitsteekt.<\/p>\n\n\n\n Er is ook een verhoging in de maat 4 inch<\/a>, en voor 2 inch focusers zijn er aparte verhogingen voor 2 inch focusers<\/a>.<\/p>","protected":false},"excerpt":{"rendered":" Riser van Starlight Instruments in de maat 3,35 inch, die je tussen focuserbasis en focuser zet om het scherpstelbereik naar buiten te verschuiven.<\/p>","protected":false},"featured_media":113522,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[3291],"product_cat":[56,3091],"product_tag":[],"class_list":["post-113523","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":92182,"url":"https:\/\/www.telescoop.nl\/en\/omegon-pro-newton-304-2432-truss-ota\/","url_meta":{"origin":113523,"position":0},"title":"Omegon Pro Newton 304\/2432 Truss OTA","author":"","date":"03-01-2026","format":false,"excerpt":"The Omegon Pro RC 304\/2432 Truss comes with an open carbon truss tube, hyperbolic quartz mirrors, a 3-inch monorail focuser, fan, three extension tubes, an adjustable mirror cell, and a Losmandy dovetail.","rel":"","context":"Similar post","block_context":{"text":"Similar post","link":""},"img":{"alt_text":"","src":"https:\/\/i0.wp.com\/www.telescoop.nl\/wp-content\/uploads\/2026\/01\/Omegon-Ritchey-Chretien-Pro-RC-304-2432-Truss-OTA-10.jpg?resize=350%2C200&ssl=1","width":350,"height":200},"classes":[]},{"id":92214,"url":"https:\/\/www.telescoop.nl\/en\/omegon-pro-newton-406-3250-lichtgewicht-truss-ota\/","url_meta":{"origin":113523,"position":1},"title":"Omegon Pro Newton 406\/3250 Lightweight Truss OTA","author":"Info telescoop","date":"03-01-2026","format":false,"excerpt":"The Omegon Pro RC 406\/3250 Lightweight Truss comes with an open carbon truss tube, quartz honeycomb primary mirror, 3-inch monorail focuser, powerful fan, Losmandy dovetail, three extension tubes, and adjustable mirror cell.","rel":"","context":"Similar post","block_context":{"text":"Similar post","link":""},"img":{"alt_text":"","src":"https:\/\/i0.wp.com\/www.telescoop.nl\/wp-content\/uploads\/2026\/01\/Omegon-Ritchey-Chretien-Pro-RC-406-3250-lichtgewicht-truss-OTA-7.jpg?resize=350%2C200&ssl=1","width":350,"height":200},"classes":[]},{"id":92206,"url":"https:\/\/www.telescoop.nl\/en\/omegon-pro-rc-355-2845-ota\/","url_meta":{"origin":113523,"position":2},"title":"Omegon Pro RC 355\/2845 - Ritchey-Chretien Truss OTA","author":"Info telescoop","date":"03-01-2026","format":false,"excerpt":"The Omegon Pro RC 355\/2845 Truss comes with an open carbon truss tube, hyperbolic quartz mirrors with honeycomb structure, 3 inch monorail focuser, powerful fans, extension tubes and a Losmandy dovetail.","rel":"","context":"Similar post","block_context":{"text":"Similar post","link":""},"img":{"alt_text":"","src":"https:\/\/i0.wp.com\/www.telescoop.nl\/wp-content\/uploads\/2026\/01\/Omegon-Ritchey-Chretien-Pro-RC-355-2845-Truss-OTA-5.jpg?resize=350%2C200&ssl=1","width":350,"height":200},"classes":[]},{"id":25767,"url":"https:\/\/www.telescoop.nl\/en\/omegon-verlengstuk-125-inch-30-mm\/","url_meta":{"origin":113523,"position":3},"title":"Omegon 1.25 inch 30mm Extension Tube","author":"","date":"25-08-2025","format":false,"excerpt":"1.25 inch extension with 30 mm length and side set screw.
