This version uses a combo stepped barrel, so it seats in a 1.25″ drawtube or a 2″ one without an adapter.\u003c\/p\u003e\n\u003cp\u003eThe body is machined from a single piece of aluminum in one machining step, and the 650 nm diode is held by an eight-screw alignment system.

It suits a visual observer setting up at a dark site, where the illuminated return spot reads clearly without a flashlight, and it suits an imager who wants the focuser axis squared before a session of long exposures. The combo barrel makes it a sensible single purchase if you own more than one reflector with different focuser sizes.\u003c\/p\u003e\n\n\u003ch3\u003e\u003cstrong\u003eKey Features \u0026amp; Design\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e0.76 mm (30\/1000″) beam aperture:\u003c\/strong\u003e the smallest Farpoint publishes for any collimator on the amateur market.

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. Laser light scattered off a mirror surface produces speckle, and a wider beam produces a larger, noisier return patch that is harder to center against the mark. Narrowing the aperture tightens the returned spot, which is what makes a small residual error visible instead of lost in the glare.\u003c\/p\u003e\n\n\u003ch3\u003e\u003cstrong\u003eRecommended Uses\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary mirror alignment:\u003c\/strong\u003e the primary job.

Machining the barrel and the diode housing from one piece of aluminum in a single step removes the tolerance stack that comes with a barrel pressed or threaded into a separate body.

The laser projects a single 0.76 mm beam down the focuser axis and reads where it lands. That makes it decisive about the secondary mirror, whose job is to sit centred under the focuser at the correct tilt, and it makes the primary check quick. Its limit is geometric: a laser reads the primary through a return path that is itself sensitive to how squarely the laser sits in the drawtube, so the last fraction of primary tilt is not where it is strongest.\u003c\/p\u003e\n\u003cp\u003eThe Cheshire has no beam at all. Its reflective pane throws diffuse light down the tube and presents an illuminated annulus against which the primary's centre mark is judged by eye. Because the reading is a concentricity judgement made on an extended field rather than a spot position, it resolves the primary far more finely, and it is unaffected by any residual tilt of the tool in the focuser. Running the laser first and the Cheshire second uses each instrument where its geometry is strongest.\u003c\/p\u003e\n\u003cp\u003eTwo details underpin the laser's own accuracy. Machining the barrel and diode housing from a single aluminum blank removes the tolerance stack that comes with a barrel pressed into a separate body, and the eight-screw mount clamps the diode at both ends with directly opposing pairs, holding it in compression so alignment survives handling and transport.\u003c\/p\u003e\n\n\u003ch3\u003e\u003cstrong\u003eRecommended Uses\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull collimation of a 2″-focuser Newtonian or Dobsonian:\u003c\/strong\u003e secondary with the laser, primary finished with the Cheshire.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePre-imaging alignment:\u003c\/strong\u003e squaring the optics before a run of long exposures, where corner coma exposes small errors.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSetup after transport:\u003c\/strong\u003e a truss Dobsonian reassembled at a dark site reads with the laser in seconds.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMid-session confirmation:\u003c\/strong\u003e the laser return is visible without white light.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFirst-time centre marking:\u003c\/strong\u003e the supplied template and triangle spots put the reference point on the primary that both tools use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eServicing a second, smaller reflector:\u003c\/strong\u003e the combo barrel steps down to 1.25″ focusers.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003e\u003cstrong\u003eCompatibility and Accessory Notes\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFocuser fit:\u003c\/strong\u003e the 2″ Cheshire takes a 2″ drawtube.

The laser projects a single 0.76 mm beam down the focuser axis and reads where it lands. That makes it decisive about the secondary mirror, whose job is to sit centred under the focuser at the correct tilt, and it makes the primary check quick. Its limit is geometric: the laser reads the primary through a return path that is itself sensitive to how squarely the tool sits in the drawtube, so the last fraction of primary tilt is not where a laser is strongest.\u003c\/p\u003e\n\u003cp\u003eThe Cheshire projects no beam. Its reflective pane throws diffuse light down the tube and presents an illuminated field against which the primary's centre mark is judged by eye. Because that reading is a concentricity judgement on an extended field rather than the position of a spot, it resolves the primary more finely, and residual tilt of the tool in the focuser does not bias it. Running the laser first and the Cheshire second uses each instrument where its geometry is strongest.\u003c\/p\u003e\n\u003cp\u003eTwo details underpin the laser's own accuracy.
