This makes the tubes much stiffer and the adjustment stability is high. The openings for the secondary are precisely fitted with turned mating parts, ensuring that the secondary spider vanes are correct and the telescope produces perfect spikes right from the start.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eFocus position optimized for astrophotography:\u003c\/em\u003e\u003cbr\u003eThe focus point is 135mm above the tube. This allows you to use different focusers and still have a comfortable working distance. With the standard focuser UNCN2-G2 you even get 80mm working distance, this even allows the use of focal reducers or a binoviewer with moderate glass path compensation. For standard correctors we recommend a 20mm spacer, which sits between the focuser. This gives you 60mm backfocus.\u003c\/p\u003e\n\u003cp\u003eNote: For visual observation you need a 2\" extension tube - \u003ca href=\"https:\/\/www.horizonastronomy.ie\/collections\/astrophotography-accessories\/products\/ts-optics-2-extension-tube-35mm\" rel=\"noopener\" target=\"_blank\"\u003eClick here\u003c\/a\u003e.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003eThe 2\" TS UNCN2-G2 RAP focuser:\u003c\/em\u003e\u003cbr\u003eA core component of the TS UNC-Newtons is the modern TS UNCN2-G2 focuser.
