To verify co llimation, view a star near the ze nith. Use a medium to high power ocular — 12 mm to 6 mm fo cal length. It is imp ortant to center a star in the center of the field to jud g e collimation. Slowly cross in and out of focus and judge th e symmetry of the star. If you see a systematic s ke w ing of the star to one side, then re - coll[...]
