Collimating your Newtonian reflector telescope with the Orion 7358 Quick-Collimation Cap is a straightforward process. Follow these steps for optimal results:
-
Insert the Collimation Cap: Begin by inserting the Orion 7358 Quick-Collimation Cap into the 1.25" focuser of your telescope.
-
Prepare for Collimation: Ensure you're in a well-lit room and the telescope tube is positioned horizontally. Place a white piece of paper inside the tube, opposite the focuser.
-
Check Initial Alignment: Remove the eyepiece and look into the focuser. Confirm that the secondary mirror is centered, and the reflections of both primary and secondary mirrors are aligned (refer to the Orion instruction manual if needed).
-
Align the Secondary Mirror: Adjust the secondary mirror's tilt to center the reflection of the primary mirror within the secondary mirror. You'll be using the secondary mirror adjustment screws for this step.
-
Align the Primary Mirror: Loosen the locking thumbscrews on the back of the telescope tube. Use the spring-loaded collimation knobs to adjust the primary mirror's tilt until the secondary mirror reflection is centered in the primary mirror.
-
Finalize Adjustment: Once centered, lightly tighten the locking thumbscrews to secure the primary mirror in place.
-
Perform a Star Test: Point your telescope at a bright star and center it in your eyepiece's field of view. Defocus the image and observe the diffraction rings. Perfectly circular rings indicate correct collimation. Slight adjustments may be needed.
