127mm f/9.4 OTA Construction - OTA Alignment (ready for alignment)

 

Here we have the tube with the mounted target, focuser and laser collimator sitting on a workbench ready to be aligned... (Click for enlarged view)

 

Sitting atop my folding workbench the main tube with paper target, focuser and laser collimation are in position to begin alignment of the focuser.

With the focuser snugly positioned inside the tube and the  drawtube fully racked out, we are ready to fire up the securely mounted laser collimator to see where the beam will strike initially. Well, it did not hit the center of the target. So adjustments to the focuser had to be made. The focuser was methodically shifted up, down , left, and right until the laser beam struck somewhere within the center portion of the target.
