TS-Optics 2" LED Collimator for RC Telescopes and all other types of telescopes
The TSRC Kolli collimator was developed by TS for Ritchey-Chrétien telescopes, but can also be used for all other types of telescopes, such as refractor, Newtonian or SC Cassegrain, made in Europe.
♦ The corrector allows precise collimation of almost all optical systems with great precision.
♦ Fits all 2" sockets with a precise 2" socket to prevent tilting
♦ LEDs are powered by 2 standard 1.5V AA batteries (batteries are not included)
♦ We recommend the collimator especially for RC, Cassegrain and Schmidt Cassegrain telescopes, as long as there is a secondary mirror center mark. This means that a first-class collimation state of the telescope can also be achieved underground.
TS RCKOLLI 2" LED Collimator for all types of telescopes
The collimator is manufactured exclusively for Teleskop-Service. It is compatible with almost all common optical systems and allows clean collimation during the day. In particular, we recommend the collimator for all Cassegrain telescopes such as Schmidt-Cassegrain, RC, Dall-Kirkham and similar types of telescopes. The collimator is very precise and the collimation result is largely independent of tilt.
Collimation of Ritchey-Chrétien telescopes and similar systems
It is well known that collimating an RC is not a simple matter. As a rule, night use on the star is necessary here. Thanks to the TS collimator, it is possible to achieve an optimal collimation result during the day, comparable to the Takahashi collimator. This means that an optimally adjusted RC telescope is always at your disposal at night. Collimation is simple and can be done by anyone. But it is important that the secondary mirror of your telescope has a center mark. Just do the following:
Place the optical tube on a table or level the telescope on its mount. It is useful to align the telescope with a homogeneous and shiny surface (paper, house wall...). Now insert the collimator into the 2" receptacle on your focuser. It helps if you align the label with the collimation screws, this makes the job easier. Press the collimator lightly with your hand from behind. This ensures that the collimator is seated optimally. on the extension Now lightly tighten the clamping screws Now turn on the collimator in Newtonian/reflector mode (red LEDs) Now look through the hole.
If the image looks like this, you can cancel the collimation process, your telescope is optimally adjusted and ready for the night.
However, if the image does not appear centered, you should start collimating to get the best result from the telescope.
Step 1 - Secondary Mirror Adjustment:
Adjust the secondary mirror with the adjustment screws until you have the center mark on your secondary mirror exactly in the middle. You will immediately see the smallest deviations, which you can easily adjust. Make sure to loosen the locking screws beforehand (if available) and that the secondary mirror is not loose after collimation.
At the end of this collimation step, the result should look like this.
Step 2 - Primary Mirror Adjustment:
Now center the outer ring by adjusting the main mirror. Make sure the locking screws are loosened beforehand. Loosen the locking screws only slightly, then adjust the main mirror, and then tighten the locking screws slightly. This procedure prevents the cell from being overloaded or completely loosened. Also, do not over-tighten the locking screws.
At the end of collimation, the result should look like this. Collimation is complete and your telescope is ready for the night.
RC telescopes with TILTING mechanism on the focuser:
Many Ritchey-Chrétien telescopes have a third collimation option, tilting the focuser. Attempts have often been made to compensate for poor collimation with this tilt, which does not work well. Therefore, you must set the tilt mechanism all the way before collimating. This ensures that the optics are optimally adjusted to the focuser.
You must use the tilt mechanism to optimally adjust the camera sensor to the telescope. This allows you to compensate for a slight misalignment of the sensor or a slight tilt of the focuser.
