TS Optics Off Axis Guider with Zeiss M68x1 connection - short design

Off axis guider for large cameras

This big off axis guider with Zeiss M68 thread connection is a consequent further development of the short TSOAG9. This model is designed for heavy cameras with large sensors. With an optical length of 16.7 mm, it also needs not much back focus. But nevertheless, it offers all options needed for professional tracking.

Advantages and characteristics

• M68x1 Zeiss thread on both sides
• Length 16.7 mm only (w/o male threads)
• Choice of three positions (120° each) for the sidewards T2 guiding cam adapter, thus you have always a good framing option for the sensor
• Free aperture of 62.5 mm: even large camera sensors can be used without vignetting
• Massive design: all connections are screwed, no clamping. This is ideal for heavy cameras.
• The guiding focus can be adjusted individually
• The prism can be shifted in order to reach an optimal position relative to the main sensor
• Internal surface with anti-reflective thread

Three connections for the prism tower

Due to the massive design, this OAG has no rotation functionality that could compromise the solid connection of heavy cameras. Three positions (3 x 120°) can be used for the guiding tower. Inappropriate prism positions relative to the main sensor (e.g. in front of an edge) are prevented. If the guiding cam collides in one position with the main camera, another position can be chosen. The two holes not in use can be closed to prevent stray light from entering the system.

Short design

The off axis guider is consequently designed for short design without compromising its stability or ease of use. All elements can also be operated when wearing gloves.

Distances to prism

• Distance from female M68 thread to prism center: 11.5 mm
• Minimum distance from prism center to T2 thread: 27 mm
