  • William Optics SCT Connection for WO Diagonals - Gold

    The William Optics SCT Connection for WO Diagonals creates a precise, threaded link between components, featuring a female M50.8 input thread and a male M48 output thread. This robust adapter adds a minimal 13.8 mm of optical length to your imaging train, ensuring a rigid, flex-free connection for your William Optics hardware.

    Precision M50.8 to M48 Adaptation in 13.8mm

    This adapter is engineered to establish a secure, non-flexing link within your optical train. It directly converts a male M50.8 thread to a male M48 thread, which is essential for connecting specific William Optics accessories or creating custom imaging configurations where a standard connection is not available.

    The 13.8 mm optical path length is a critical specification for achieving correct spacing with flatteners or reducers that require precise back focus. 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: Connects securely to accessories with a male M50.8 output thread, common on some William Optics flatteners and accessories.
    • Male M48 Thread: Provides a standard 2-inch filter thread for connecting to cameras, filter wheels, or other M48-threaded accessories.
    • Optical Path (13.8 mm): Adds a defined and minimal length, a known value critical for maintaining proper back focus calculations in an imaging setup.

  • 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 exactly 13.8 mm of optical length to your setup. This is a critical measurement to factor into your back focus calculations when using reducers or flatteners.

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

    Yes, this adapter is designed for that specific purpose. 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?

    Based on the specified threads (M50.8 female and M48 male), this adapter is not designed to connect a standard William Optics diagonal to a standard SCT rear cell, which typically requires a female 2"-24 TPI SCT thread. This adapter is intended for connecting components within an existing M50.8/M48 threaded system. Always verify the threads on your specific diagonal and telescope before purchasing.

    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.
