The mirror gets a center mark first, because without one a laser and a Cheshire have no reference to align to. The laser then sets the focuser axis and brings the secondary into position quickly, including in the dark. The Cheshire refines the primary using reflected light and no batteries. An autocollimator takes the alignment further still by stacking multiple reflections, which makes residual error easier to see.\u003c\/p\u003e\n\n\u003ch3\u003e\u003cstrong\u003eWhat sets the Farpoint lasers apart\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eEach body is machined from a single piece of aluminum in one machining step, which keeps the barrel and the laser axis concentric.

The 0.76 mm (30\/1000\") beam aperture is the smallest Farpoint publishes for any collimator on the amateur market, which reduces speckle and makes the return spot easier to read against the center mark.

If the beam leaves at an angle to the barrel axis, every adjustment it suggests is wrong by that angle — and the error is invisible, because the tool looks like it is working. Farpoint addresses this at two points. Machining the barrel and diode housing from a single aluminum blank in one step removes the stacked tolerances you get when a barrel is pressed or threaded into a separate body. The eight-screw arrangement then constrains the diode at both ends with directly opposing pairs, so it is clamped rather than pushed against a spring or a single bearing face, and it stays put when the tool is handled or dropped into a case.\u003c\/p\u003e\n\u003cp\u003eThe 0.76 mm beam aperture works on the same principle from the other direction.

The laser projects a beam down the focuser axis, so it shows immediately whether the secondary is centred and tilted correctly; that is a geometric question, and a beam answers it in seconds, in the dark, without your eye at the eyepiece. What a laser is less good at is the final primary tilt, because the return spot is a small bright point judged against a mark, and small errors are easy to under-read.\u003c\/p\u003e\n\u003cp\u003eThe Cheshire inverts both strengths. Its reflective pane illuminates the optical path and presents a wide, evenly lit field, so the primary's centre mark and the reflected stack of apertures line up visually with much finer resolution than a spot on a target.

What takes care on a large scope is the handling: the primary comes out of its cell, and a 16\" or 20\" mirror wants a cleared, padded surface and an unhurried hour. Eight targets are supplied so a first attempt you are not satisfied with costs nothing, and Farpoint publishes preparation guides and downloadable collimation references if you would like to read the sequence through beforehand.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy does the centre mark matter so much on a big mirror?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eLarge primaries usually come with fast focal ratios, and a fast Newtonian has a tighter tolerance for primary tilt. A placement error therefore has a larger optical consequence — and because every tool references the same mark, the error stays consistent and invisible rather than showing up as a disagreement between tools.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy triangles rather than a round dot?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA triangle gives you edges to read against. The edges meet the outside of the illuminated field through a Cheshire, so you match straight lines to a boundary rather than judging whether one circle sits centred inside another.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat size mirrors does this fit?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003ePrimary mirrors from 12\" to 26\" in diameter.
