Each optical tube assembly is an f\/7 apochromatic refractor built on precision aligned ED glass, and each one ships ready to accept a Lunt hydrogen alpha module later. You choose the aperture, then decide when to add the solar side.\u003c\/p\u003e\n    \u003cp\u003eFour apertures cover the range. The 70mm works at 420mm focal length, the 80mm at 560mm, the 100mm at 714mm and the 130mm at 910mm, so every tube holds the same f\/7 focal ratio. Smaller tubes stay travel friendly at around five and a half pounds, while the 130mm delivers the most resolution for deep sky imaging.\u003c\/p\u003e\n    \u003cp\u003eA dual speed 10:1 rack and pinion focuser handles fine adjustment, and a ring or clamshell assembly with a Vixen style dovetail lets you mount on standard saddles. When you want the Sun, swap the focuser for a Lunt hydrogen alpha module and blocking filter and the same tube reaches 0.7 Angstrom bandwidth or tighter. A fitted hard case protects the tube in transit.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"kt-hero-img\"\u003e\n    \u003cdiv class=\"kt-sq\"\u003e\n      \u003cimg
