If you're still worried after you purchase the Astro Systems Collimating Tool Set, don't be. The good folks at Astro Systems have included a 14 page instruction booklet that will take you step-by-step through the collimation process.
Axial beam lasers are subject to minor centering errors on the return spot from the primary mirror that can be difficult to detect. These minor errors can make a substantial difference in achieving accurate collimation on shorter (f/4.5 or less) telescopes. When using a Barlowed laser, it is possible to achieve 20 thousandths of an inch centering or better on the return beam. This is usually precise enough collimation for general observing, but can be followed up with our autocollimator for tack sharp images. A thorough 12 page instruction booklet is included as well as the 2 AA batteries on which it operates.
