Also, remember to keep the telescope in the horizontal position so if you drop something to the tube, it will not slide down on the primary mirror. You dont have to make these adjustments very often in the future, so make sure you do a good job here. It will need adjustment if, as in Figure 2d, the secondary mirror is centered under the focuser and the reflection of the primary mirror is centered in the secondary mirror, but the small reflec - tion of the secondary mirror (with the "dot" of the collimation The simplest method of polar alignment is simply to aim the RA axis at . You will need an optional tool to perform collimation. This so-called polar alignment is not hard to achieve. The only special tool is the collimation cap which is a standard cap with the hole in the middle and reflection surface inside. The second warning is not to point the telescope towards the sun- ever! This test verifies the actuators have enough range of movement once they are in space, at their operational temperature of about 40 K (or about minus 388 degrees Fahrenheit / minus 233 degrees Celsius), to put the telescope's primary mirror into its correct shape so it can accurately survey the universe. Step 3: Center your primary mirror's sweet spot in the eyepiece's field of view. While doing that, keep looking through the cap hole in the focuser. It means that you have to see the reflection of the primary mirror on the secondary mirror perfectly centered. The steps in the commissioning process include: Segment Image Identification. Unfortunately though, it is something that you have to repeat over and over again, particularly if you move the telescope around to different observing sites as its very easy to jolt them back out of alignment. This step-by-step, beginners guide shows you how. Scroll down for purchase. There is a set of 6 knobs. You would be surprised how many lasers come not aligned.
