The openings for the secondary are precisely fitted to ensure that the secondary spider vanes are perfectly correct and the telescope produces perfectly thin spikes right from the start.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFocus position optimized for astrophotography:\u003c\/strong\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 get 80mm working distance. For standard correctors like the Baader MPCC or the TS-Optics MAXFIELD corrector we recommend the 20mm spacer, which goes between the focuser. This gives you then 60mm backfocus. For visual observations with an eyepiece you need an additional  2\" extension tube.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe 2\" TS UNCN2-G2 RAP focuser:\u003c\/strong\u003e\u003cbr\u003eA core component of the TS UNC-Newtons is the modern TS UNCN2-G2 focuser.
