Met deze verlengbuis voor een focuser van 2,5 inch zet je de focuser 2,25 inch verder van de basis, ongeveer 5,7 cm.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">De verlengbuis van Starlight Instruments heeft een diameter van 2,5 inch en komt tussen de basis en de focuser. Dat is handig op een <a href=\"https:\/\/www.telescoop.nl\/en\/telescopes\/reflector-telescopes\/reflector-ota\/\">losse Newton-buis<\/a>, bijvoorbeeld als je er een focuser op zet die lager bouwt dan de oude, zodat het brandpunt buiten het bereik van de uittrek valt.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Meet eerst hoeveel extra lengte je nodig hebt, bijvoorbeeld door met de camera te kijken hoeveel je focuser nog tekortkomt. Te veel verhoging kost je bereik naar binnen, en dan haal je visueel soms geen focus meer. Controleer ook of de verhoging past bij de 2,5 inch maat van jouw basis en focuser.
