Do Maksutov telescopes need collimation?

Collimating a Maksutov-Cassegrain Maksutov-Cassegrains typically rarely need collimation, but if yours is out of collimation you’re in luck. Most Maks have small screws behind the primary mirror which should allow you to tilt it.

How do you collimate a Maksutov telescope?

Take your telescope out at dusk and let it acclimate to the out- side temperature; this usually takes 30-60 minutes. When it is dark, point the telescope upwards at a bright star and accurately center it in the eyepiece’s field of view. Slowly de-focus the image with the focusing knob.

Do Cassegrain telescopes need collimation?

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 you focus a Maksutov Cassegrain telescope?

The focusing knob, which moves the primary mirror, is on the rear cell of the telescope just below the star diagonal and eyepiece. Turn the focusing knob until the image is sharp. If the knob will not turn, it has reached the end of its travel on the focusing mechanism.

Are Maksutov Cassegrain telescopes good?

Although reasonably popular in small sizes, large Maksutov-Cassegrains are fairly uncommon. A well-built Mak-Cass can be an excellent telescope, but they are primarily intended more for visual use or planetary imaging and not so much for deep-sky photography.

How do you use a collimation cap?

Point the telescope at a lit wall and insert the collimating cap into the focuser in place of a regular eyepiece. Look into the focuser through your collimating cap. You may have to twist the focus knob a few turns until the reflected image of the focuser is out of your view.

How does a collimation cap work?

Collimation cap: A collimation cap, or sight tube, is a plug that fits in your reflector’s focuser. It has a small central hole. Although it’s mainly used to ensure that your secondary mirror is aligned with respect to your focuser, it can also be used to ensure correct alignment of the secondary and primary mirrors.

Does a Schmidt-Cassegrain telescope require collimation?

To get the best performance from your Schmidt-Cassegrain (SCT) or EdgeHD telescope, its optics must be collimated—properly aligned within the telescope.
