Instead of 1.25 inches and 2 inches, the two sections of the barrel measure out (with digital calipers) to 1.254 inches and 2.002 inches. Usually the barrels are 0.003 inches smaller than the tube they’re supposed to fit into, so this collimator is well below our standards. We tried to insert it into both a 1.25 inch tube as well as a 2 inch tube (both tubes are accessories we sell, so they’re intended to accept things of this sort), and it fit into the 1.25 inch tube, but not the 2 inch tube. In other words, this works as a 1.25 inch collimator, while having the body of a 2 inch collimator. The snugness of the 1.25 inch barrel could actually be a benefit, as it means the collimator will wiggle less in your focuser.
Farpoint 650nm Laser Collimator – 1.25 Inch / 2 Inch
Farpoint 650nm Laser Collimator – 1.25 Inch / 2 Inch laser bodies are precisely machined from a single piece of aluminum in a single machining step, resulting in perfect alignment. A collimator is a simple tool that helps align the optical axes of the mirrors of a Newtonian reflector, a process called collimation. Offering the smallest aperture of any other laser in the amateur astronomy market, Farpoint lasers feature an aperture (0.76mm or 30/1000 of an inch) producing less speckling and more precise reading of the laser beam’s position on the telescope mirror.
Features a 1.25″ and 2″ combo stepped barrel, an extra bright 650nm red laser, and superior EIGHT screw alignment arrangement ensuring that BOTH ends of the laser diode are held in place by two sets of directly opposing screws for precise and lasting alignment.
Fabricated with a rugged, smooth red laser body to best show the position of the laser return beam on the laser body (red shows tightest beam with the least speckling). The easy to use switch has a positive action and it is protected by an aluminum ring to prevent inadvertent power cycling. This tool fits nicely into the palm of your hand, and will provide years of trouble-free, accurate mirror alignments.
Includes a mirror spotting template and triangle center spots to help simplify the process of center spotting a primary mirror. For Newtonian Reflectors only.
