Product Description
Red laser collimator is very convenient to calibrate targets!
Using it when you are taking astronomy classes can highly improve your speed
No telescope can align its optical axis for a long time, even if it is already factory calibrated. The Newtonian reflection telescope is very sensitive to the optical axis; a slight movement of the calibration screw can deflect the entire optical axis. Its precision is so high that it goes out in the car, the optical axis will have a small deviation, and sometimes it will completely collapse.
Even if the lens barrel is pointed differently, the optical axis will be different. (An interesting experiment is to point the same star through the equatorial mount, then move the equatorial mount's right ascension axis from left to right through the field of view to observe the optical axis.Offset).
This is why you should choose a star to calibrate, not the target of interest (Jupiter or Moon). If you observe deep space, you feel that the slight deviation can be tolerated, and then you will not be calibrated when you turn to planet observation. This is actually very risky. The good way is to check the optical axis before each observation, just like checking the mailbox and the tire before driving far away.
