Tilter TS-Optics M90 for 6" and 8" RC Tubes

Tilter TS-Optics M90 for 6" and 8" RC tubes

Tilter Adapter TS-Optics M90x1
You have your telescope perfectly aligned and enjoy fine stars on the optical axis, but your camera shows distorted stars in one corner. The larger the camera sensor, the stronger the effect. Almost all astrophotographers are familiar with this "bad corner". The most likely causes are:

♦ The telescope field is slightly tilted. This can occur due to a simple focuser or due to slightly tilted optics.

♦ The camera sensor is not exactly perpendicular to the optical axis. Manufacturers glue the sensors to the body. Accuracy is sufficient for normal applications. But high resolution optics show this error.

The tilt adapter from TS-Optics is a possible solution:
With three adjustment screws, the focuser is tilted sensitively and thus adjusts the camera sensor exactly to the optical field of the telescope. With the locking screws, the position is fixed. The elongated stars in the corner become round again. This time-consuming process should only be done once. However, we recommend not to change the orientation of the adapter to the camera sensor again.

Another possible application for self-building and upgrading refractors:
Many basic refractor telescopes have good optics, but do not offer the possibility of adjustment. If you install the GSRCJ90 between the objective and the tube, you can tilt the objective and thus align it optimally with the tube. All you need is an adapter from the objective to M90x1 and the subsequent adaptation to the tube.

Two Allen keys (3 + 2 mm) are required to adjust the adapter. These are not included.
