This unique and innovative collimator combines the LightPipe with the SightTube into one easier to use, lower-cost tool. The LightPipe functions just like a Cheshire collimator, but with two important differences. First, the acrylic lightpipe will not darken or corrode with time, like the aluminum reflector used on a Cheshire. Second, the lightpipe is non-directional to illuminate. When using a flashlight at night to illuminate the tool, any angle works, unlike the temperamental Cheshire.
The 2-in-1 collimator accurately aligns optics in Newtonian telescopes (LightPipe) as well as accurately aligning the secondary mirror under the focuser (SightTube). The 2" version is easier to use in telescopes having a long focal length of (70"+) and larger proportional secondary mirrors such as those in short f/ratio telescopes (f/3.5-f/4.5) or imaging telescopes. Save time and money with this 2 in 1 tool.
Precision-made anodized aluminum, acrylic insert and stainless steel crosshair wires. Includes 14 page instruction booklet.
