SVBONY Red Lasor Collimator Using Methods:
The process of calibration is repeated (check-adjust-check-adjust....). In addition to the following points, there is no difficulty or risk in the whole process:
- The big screw in the middle that fixes the secondary mirror, never touch it.
-The three fine-tuning screws should be very gentle when screwing in and out, not too loose or too tight
- If you screw one of the screws out, the other two will be screwed in.
- When rotating, be sure to move small: a very irregular mirror can be rotated half a turn at a time, but the final adjustment is still very small.
- Every time the rotation, the star will move because of this adjustment, it must be pulled to the center again.
For Newtonian reflection telescope, calibration usually takes two steps: first adjust the secondary mirror to the appropriate position (using the calibration eyepiece), then adjust the primary mirror
