Product Description

SVBONY Laser Collimator 1.25'' Metal with 2" Adapter

It's great for a student, you will need it when you are learning astronomy class or when attending an astronomical society in college or school

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.

SVBONY Laser Collimator for Newtonian Telescopes

7 Level Ajustable Brightness Beam

Aim at the target anytime,anywhere,even during the daytime can also be used normally.

7 settings of brightness is useful and easier on the eyes and great for different areas of light

Removable 2" adapter

This is a newest 1.25" laser collimator includes removable 2" adapter;the triple cemented lens to improve the stability of dot;it's designed for accurate collimation of all Newtonian and SCT reflector telescopes

Easy to target

It is very easy to simply look at the laser target and adjust the telescope until the red dot is centered. no need to keep looking at the cap in the telescope's eyepiece

Durable design

SVBONY Red Laser Collimator is made of all-metal material and has a long service life.

  • Package List:

Warning:

Do not look directly into the laser beam! Permanent eye damage may result!

Avoid prolonged skin exposure to laser rashes or burns may occur!

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
