SBIG STX Self Guided Add on for FW7-STX, FW5-STX Filter Wheels

A cutting-edge accessory for astrophotography enthusiasts, the STX Self Guided Add-on is designed to seamlessly integrate with FW7-STX and FW5-STX filter wheels. This innovative product, crafted by the reputable brand Sbig, transforms your filter wheel into a self-guiding powerhouse, enhancing the accuracy of long exposure astrophotography, especially when used with commercial SCTs.

The STX Guider is equipped with a KAI-0340 CCD, boasting 640 x 480 pixels at 7.4u. This CCD is strategically positioned at the front of the STX filter wheel, enabling it to capture light from guide stars before it passes through the filters. This unique feature addresses the common challenge of locating bright stars when guiding through dark or narrowband filters.

The guiding CCD in the STX Guider is identical to the sensor used in the ST-i autoguider, ensuring consistent, high-quality results. The optical elements that transfer light from the pick-off mirror to the CCD also function as a 0.7X focal reducer, effectively doubling the field of view of the guiding CCD. This results in a greater selection of guide stars, enhancing your astrophotography experience.

The STX Guider is designed with user-friendly features, including two smaller adjustment knobs for focus and pick-off mirror movement, helping to avoid vignetting. A third knob on the side of the unit locks the adjustments in place once optimal focus is achieved. The STX Guider is also fully compatible with the AO-X adaptive optics accessory, offering even more versatility.

Despite its robust functionality, the STX Guider is compact and lightweight, weighing in at just 1 lb. It consumes only 1.1" of back focus and requires no additional adapters, making it a convenient and efficient addition to your camera setup. A short cable is included to connect the STX Guider to the remote guide head port on your camera.

In summary, the STX Self Guided Add-on is a durable, high-quality, and stylish accessory that enhances the functionality of your FW7-STX and FW5-STX filter wheels, making it an essential tool for any serious astrophotographer.
