Add to Cart
This Brunson 381-1 Alignment Telescope is basically the same as the Brunson 381 Alignment Telescope, with the difference being the 90 degree eyepiece. This compact Alignment Telescope is only 9-1/2 inches long and has a 1.750 barrel diameter. The 90-Degree eyepiece allows mounting in even tighter locations than the 381. This has a internal Paired-Line Autoreflection Target, and a filar, bifilar reticle in the eyepiece. The image is erect and with the low-reflection coated optics, offers 20X magnification at 2 inches and 30X at infinity. This is an excellent alternative to the Davidson Optronics compact line telescopes
