Description
No telescope can align its optical axis for longer periods of 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.
Even if the lens barrel is differently aligned, the optical axis changes. (With a star telescope, a star is displayed on the equator mount. When the equator mount moves, the lens tube of the telescope also moves towards the equator movement. If you see this star again, the optical axis of the telescope is not permitted. You need to set it again.)
For this reason, you should select a star to be calibrated, not the desired target (Jupiter or Moon). When you observe space, you feel that the slight deviation can be tolerated, and you will not be calibrated when you turn to planet observation. This is actually very risky.
It is best to check the optical axis before each observation, just like the fuel tank and tyres before each ride.
Adjustable collimator
This new collimator has a hole that can be adjusted with a spanner (included) to adjust the alignment of the collimator. If the collimator loses collimation due to impact during transport or for other reasons, you can align the optical axis.
The new collimator can be adjusted to extend its service life.
More accurate
- 3 mm red dot instead of a red ball increases the precision of the collimator;
- Premium spherical module makes the collimator more sensitive and accurate while being more user-friendly.
- The material of the collimator lens is triple cemented which is very important to improve the stability of the red spot.

Replaceable lithium battery includedYou can use the item directly once you receive it, and do not need to buy the battery separately. The collimator is much safer for your eyes than others due to its output power of less than 5mW. |
On/off switch.On/off switch is easy to use and improves ease of use. |
2 sizes.With the Svbony 1.25 inch collimator and a 2 inch adapter, everyone can easily collimate 1.25 inch and 2 inch reflector telescopes. |
Long-lasting.It can also be used in extreme cold (30/-22 ℉) and without affecting the effect. Metal material body, undeformed, sturdy and durable. One-time purchase for long-term use. |
