Do Maksutov Cassegrain telescopes need collimation?
Collimation is the alignment of a telescope’s optics with its mechanical axis. Your Maksutov-Casegrain’s optics were colli- mated at the factory and should generally not need adjustment unless the telescope has been handled roughly. If the image is unsymmetrical, the scope is out of collimation.

How do you collimate a Maksutov Cassegrain telescope?
Collimating an SCT is simply a matter of adjusting the three screws on the secondary mirror. This changes the tilt of the mirror and aligns it with the (fixed) primary mirror. The tilt of the mirror is tested by viewing an out-of-focus star image through the telescope.
Why is the collimator important?
Proper collimation is one of the aspects of optimising the radiographic imaging technique. It prevents unnecessary exposure of anatomy outside the area of interest, and it also improves image quality by producing less scatter radiation from these areas.
How do you focus a Maksutov Cassegrain telescope?
Maksutov-Cassegrain telescopes are capable of focusing on objects that are quite close, so you can view fine details of objects that are nearby. Try focusing on a flower or insect at close distance to enter a normally unseen microscopic world.

Do Schmidt-Cassegrain telescopes require collimation?
Your telescope must be the same temperature as the ambient air. Precise collimation is essential to good performance for any Schmidt-Cassegrain telescope. For SCTs, it’s done by small adjustments to the tilt and position of the secondary mirror in its cell.
How do I know if my telescope is collimated?
You want to see a diffraction pattern of concentric circles appear around it. Basically, this refers to circles around the star that might look a little wiggly. If the circles you see are not concentric, then your telescope needs to be collimated.
How hard is it to collimate a telescope?
Fortunately, collimating a reflector is simple. Once you get the process down, it takes only a few minutes. A laser collimator emits a beam that bounces off the primary and secondary mirrors in a reflector and (hopefully) back onto the collimator’s target.
Is collimation of a Maksutov telescope difficult?
Collimating a Maksutov telescope isn’t as difficult as some people think it is. No, the secondary mirror of a Maksutov is painted onto the corrector plate, and does not need collimation.
Do all telescopes have to be collimated?
All telescopes, reflector, refractor, radio, etc, have to be collimated somehow some way. If there is something that moves, an OTA, a focuser, a mirror for focusing, a diagonal, et al, then the system must be collimated and will be subject to collimation adjustments as it is used.
Do Maksutov’s get misaligned over time?
Occasionally they may, if they’ve become misaligned because of being dropped or handled roughly, but in general, no, because the collimation is set at the factory. Some Maksutovs are designed to be collimated by the user and others arent; the ones that are usually have three small screws for that purpose.
Can a Maksutov Cassegrain telescope be adjusted by 3 screws?
In the case of a Maksutov Cassegrain telescope, the secondary mirror is typically and aluminized portion of the forward Meniscus lens. As such, the secondary typically cannot be adjusted by means of a three screw system. Hypothetic… Not with normal use.
