  • William Optics SCT Connection for WO Diagonals - Gold

    The William Optics SCT Connection for WO Diagonals turns a standard 2" push-in diagonal into an SCT diagonal, with a female M50.8 input thread and a male M48 output thread. It adds 13.8 mm of optical length.

    Precision M50.8 to M48 Adaptation in 13.8mm

    This adapter threads onto the male 2" (M50.8) SCT thread of a Schmidt-Cassegrain telescope, and its male M48 thread takes a William Optics 2" diagonal once the diagonal's push-in nosepiece is removed.

    Its optical length is 13.8 mm. Its all-metal construction and signature gold anodized finish ensure both durability and a perfect aesthetic match with other William Optics components.

    • Female M50.8 Thread: Threads onto the male 2" (M50.8) SCT thread on the rear cell of a Schmidt-Cassegrain telescope.
    • Male M48 Thread: Screws into a William Optics 2" diagonal in place of its push-in nosepiece.
    • Optical Path (13.8 mm): Adds 13.8 mm to the light path.

  • What are the exact thread types on the William Optics SCT Connection adapter?

    The adapter features a female M50.8 thread on the side that accepts incoming light and a male M48 thread on the output side.

    How much length does the William Optics SCT Connection add to an optical path?

    This adapter adds 13.8 mm of optical length.

    Can I use this William Optics adapter to connect a flattener with a male M50.8 thread to my camera's M48 T-ring?

    William Optics designed it to fit a WO 2" diagonal to an SCT; it will only fit a flattener whose output is a male 2" (M50.8) SCT-type thread. The female M50.8 side will thread onto your flattener, and the male M48 side will connect to any accessory with a female M48 thread, such as a 2" filter wheel or a camera-specific M48 adapter.

    Will this William Optics adapter connect my 2" diagonal to a Celestron 8" SCT?

    Yes, that is what it is for. Remove the push-in nosepiece from your William Optics 2" diagonal, thread the male M48 side into the diagonal and thread the female M50.8 side onto the telescope's 2" SCT rear thread. It turns a standard 2" push-in diagonal into an SCT diagonal.

    What is the benefit of a threaded connection over a slip-fit adapter?

    A fully threaded connection, like the one provided by the William Optics SCT Connection, prevents any sag, tilt, or wobble in the optical train. This rigidity is critical for astrophotography to ensure stars remain sharp and round across the entire image field.

    What does the "Gold" in the William Optics SCT Connection name signify?

    The "Gold" refers to the durable, gold-anodized finish. This not only protects the CNC-machined aluminum adapter from scratches and corrosion but also provides a premium, aesthetic match to other William Optics telescopes and accessories.
