  • RASA 8 Filter Holder - M54 Threads

    The RASA 8 Filter Holder integrates standard 2" mounted filters into the optical path of a Celestron RASA 8" telescope, designed specifically for cameras with M54 threads requiring exactly 17.5mm of backfocus. This adapter allows imagers using cameras like the ZWO ASI2600 Duo to seamlessly add filtration to their RASA 8 setup without altering the critical backfocus distance.

    Add 2" Filters to a RASA 8 with M54 Cameras

    This two-part adapter is engineered to replace the RASA 8's factory-installed optical window and standard camera adapter flange. Installation involves removing the original window, placing a standard 2" mounted filter into the holder, and then securing the holder to the RASA using the telescope's stock lock ring. The design thoughtfully includes access slots, ensuring you can still reach the RASA's collimation screws for fine-tuning optical alignment after the holder is installed.

  • What kind of camera is the RASA 8 Filter Holder designed for?

    This RASA 8 Filter Holder is specifically for cameras that use M54 threads for connection and have a 17.5mm backfocus requirement. The ZWO ASI2600 Duo is given as an example of a compatible camera.

    How do I install the RASA 8 Filter Holder?

    To install the holder, you must first remove the optical window that comes with the RASA 8. Then, you install your 2" mounted filter into the holder. The holder assembly then replaces the RASA's standard camera adapter and is secured using the original lock ring that came with your telescope.

    Can I still collimate my RASA 8 with the filter holder attached?

    Yes. The RASA 8 Filter Holder includes slots in its design that allow you to access the collimation screws on the RASA's front lens group, even when the holder and camera are installed.
