TS Optics focuser collimation-Tilting-with M117 Thread (49645)

The TS Optics focuser collimation tilting device with M117 thread is designed for precise adjustment of the focuser alignment on GSO RC telescopes, specifically for models 10 inches and larger. This accessory is especially useful for astrophotographers using full-frame cameras, as it allows for fine-tuning of the focuser's tilt to improve off-axis image sharpness. While cameras with APS-C or smaller sensors generally do not require this adjustment, full-frame sensors benefit from enhanced field definition and sharper images at the edges.

This adjustment device is an effective solution for achieving optimal collimation and image quality in large GSO RC telescopes, especially when using full-frame imaging sensors.

Installation is straightforward:

• Remove the focuser from the telescope

• Screw the tilting device onto the telescope

• Secure the device using the small set screws

• Re-attach the focuser to the tilting device
