Je schuift hem in de 2 inch huls zoals een oculair, en daarna doe je de fijne scherpstelling met de helicale ring in plaats van met de grote knop van je telescoop.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Dat heeft een praktisch voordeel. Aan de telescoopfocuser draaien brengt trilling in de buis en daarmee in het beeld. De helicale ring zit dicht bij de camera en beweegt vloeiend, zodat het beeld rustig blijft terwijl je scherpstelt.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-3 is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\"><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2026\/01\/Omegon-spiraalvormige-helicaalfocuser-2-2.jpg\" alt=\"Omegon helicale microfocuser van 2 inch voor fijne scherpstelling\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2026\/01\/Omegon-spiraalvormige-helicaalfocuser-2-1.jpg\" alt=\"Omegon helicale microfocuser van 2 inch voor fijne scherpstelling\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2026\/01\/Omegon-spiraalvormige-helicaalfocuser-2-.jpg\" alt=\"Omegon helicale microfocuser van 2 inch voor fijne scherpstelling\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2026\/01\/Omegon-spiraalvormige-helicaalfocuser-2-3.jpg\" alt=\"Omegon helicale microfocuser van 2 inch voor fijne scherpstelling\" title=\"\"><\/figure><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\">Helicaal in plaats van tandheugel<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Bij een helicaal ontwerp schuift de trekbuis via een schroefdraadbeweging naar buiten. Je draait aan een brede ring en de camera verplaatst zich in zeer kleine stappen.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">De scherpstelweg is 40 mm. Op de buis zit een millimeterschaal, zodat je een gevonden focuspositie kunt noteren en later terugvinden.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Sterk genoeg voor een echte camera<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Het draagvermogen bedraagt 4 kg, ruim boven wat de meeste planeetcamera's en spiegelreflexen wegen. De optische lengte van 57 mm blijft daarbij beperkt, zodat je zelden backfocus tekortkomt.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Aansluiten op wat je al hebt<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">De telescoopzijde past in elke 2 inch focuser en heeft daarnaast een M48-binnendraad. Aan de camerazijde zit eveneens M48, zodat je filters en adapters kunt doorschroeven.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Featured accessories<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Deze microfocuser combineer je goed met een Crayford-focuser van 2 inch, waarbij de Crayford de grove instelling doet en de helicaal de fijne. Voor maan- en planeetwerk is een maanfilter een logische aanvulling.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">For whom yes and for whom no<\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li>\u2713 Planeet- en maanfotografen die het scherpstelpunt exact willen raken<\/li><li>\u2713 Wie trilling tijdens het scherpstellen wil vermijden<\/li><li>\u2713 Bezitters van een focuser zonder fijnafstelling<\/li><li>\u2717 Wie een complete vervanging van de telescoopfocuser zoekt<\/li><li>\u2717 Opstellingen zonder ruimte in de backfocus: de focuser voegt 57 mm toe<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Specifications<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Type scherpstelling<\/strong><\/td><td>Helical<\/td><\/tr><tr><td><strong>Focusing road<\/strong><\/td><td>40 mm<\/td><\/tr><tr><td><strong>Telescope connection<\/strong><\/td><td>2 inch en M48 binnendraad<\/td><\/tr><tr><td><strong>Camera side<\/strong><\/td><td>M48<\/td><\/tr><tr><td><strong>Carrying capacity<\/strong><\/td><td>4 kg<\/td><\/tr><tr><td><strong>Optical length<\/strong><\/td><td>57 mm<\/td><\/tr><tr><td><strong>Height<\/strong><\/td><td>55 mm<\/td><\/tr><tr><td><strong>Diameter<\/strong><\/td><td>70 mm<\/td><\/tr><tr><td><strong>Weight<\/strong><\/td><td>269 g<\/td><\/tr><tr><td><strong>Series<\/strong><\/td><td>Advanced<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">You can find more focusers and parts for this merk on the <a href=\"\/en\/brands\/omegon\/\">Omegon merk Page<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"<p>Helicale microfocuser van 2 inch met 40 mm scherpstelweg, millimeterschaal, M48-schroefdraad en 4 kg draagvermogen.
