Starlight Xpress TRIUS PRO-694 Midi Combi

The Combi design integrates the camera, filter wheel, and off-axis guider into a single, unified unit. This significantly reduces cable clutter and mechanical flexure, which are common issues when assembling these components individually, leading to more reliable tracking and easier setup.

The OAG is highly effective, but its performance depends on your telescope's focal length and the availability of guide stars. Because it picks off light from the edge of the optical path, you will need to ensure your telescope provides a sufficiently large corrected image circle to find a suitable guide star.

The Midi filter wheel is specifically designed to accommodate 1.25-inch mounted filters. Ensure your filter set matches this size, as larger or unmounted filters will not fit the carousel.

Yes, the Lodestar PRO is a separate, high-sensitivity camera that mounts into the OAG port. While it is designed to work seamlessly with this system, it can be removed and used independently for other guiding applications if needed.

Starlight Xpress provides robust driver support for their cameras, making them compatible with most major astrophotography acquisition software, including ASCOM-compliant programs like Sequence Generator Pro, N.I.N.A., and Maxim DL.

The Sony ICX694 sensor used in this camera is highly regarded for its low read noise and high quantum efficiency. It is particularly well-suited for deep-sky objects, offering excellent sensitivity and clean, low-noise data that is relatively easy to process.
