SBIG FW8G-Aluma Self Guided Filter Wheel for STT Cameras

After careful design and engineering, the SBIG FW8G-Aluma Self Guided Filter Wheel emerges as an innovative accessory for STT cameras. This high-quality, 8-position filter wheel is specifically crafted for the Aluma Series cameras, offering a compact and user-friendly solution for photographers and videographers alike.

The FW8G-Aluma is more than just a filter wheel; it's a comprehensive imaging tool. It features a built-in guiding CCD and associated optics, strategically positioned in the front cover, ahead of the filters. This unique design ensures optimum guiding sensitivity for all filter slots, enhancing your image capture capabilities.

However, due to backfocus requirements, CLA camera lens adapters are not compatible with this cover. But worry not, as a lower profile standard cover, devoid of a guider, is available as an accessory. This standard cover can be easily swapped with the self-guiding cover when imaging through a camera lens is required.

The carousel of the FW8G-Aluma holds eight 36mm filters, with inserts available for 1.25" filters. These 36mm filters provide unvignetted imaging for the largest Aluma sensors, ensuring high-quality image capture. The Aluma wheels also boast a positive centering mechanism that precisely aligns each filter in the exact same position every time. This single-pixel accuracy completely eradicates ghost images of dust spots and other artifacts after flat-fielding.

The FW8G-Aluma also includes a built-in focal reducer and autoguider. The pick-off mirror and camera focus can both be adjusted and locked using simple thumbscrews. This built-in autoguider system eliminates issues with flexure, mirror shift, and other mechanical problems that can degrade guiding accuracy.

Please note, the FW8G-Aluma is thicker and does not permit the use of CLA lens adapters. However, interchangeable plates are available to switch your wheel between FW8G and FW8S configurations, offering versatility and adaptability for your photography needs.

In conclusion, the SBIG FW8G-Aluma Self Guided Filter Wheel is a durable, high-quality, and innovative accessory that enhances the capabilities of your STT cameras.
