  • Daystar Quantum Front Wedge Plate - T-Thread

    The Daystar Quantum Front Wedge Plate (Q3GWTF) provides the essential mechanical interface for using a Quantum-series filter in an off-axis configuration on a Schmidt-Cassegrain Telescope, featuring a secure female T-thread (M42x0.75mm) connection. This purpose-built plate is physically wedged to correct the optical alignment for an off-axis light path and accepts accessories like the GM2DT 2" drawtube snout for mounting.

    Off-Axis SCT Adaptation with M42x0.75mm T-Threads

    This front plate is the key to mounting a Daystar Quantum filter away from the primary optical axis of an SCT. The integrated wedge provides the necessary tilt to maintain optimal filter performance when used with a sub-aperture mask or a secondary instrument. Its female M42x0.75mm T-threads offer a universal and rigid connection point for your telescope-side adapters.

    Accepts 2" Drawtube Snouts and SCT Thread Adapters

    Designed for flexibility within the Daystar ecosystem, the Q3GWTF plate is compatible with key mounting accessories. It directly accepts the GM2DT 2" drawtube snout, allowing you to insert the entire filter assembly into a 2" focuser. It also pairs with the GF2SCTT SCT adapter for direct attachment to a telescope's rear cell, creating a solid, threaded imaging train.

  • What is the purpose of the wedge in the Daystar Quantum Front Wedge Plate?

    The wedge is a physical tilt built into the plate. It corrects the angle of the light path for a Daystar Quantum filter when it is used in an off-axis position on a Schmidt-Cassegrain Telescope (SCT). This ensures the filter's etalon performs correctly and maintains a uniform bandpass across the solar disk.

    How do I connect the Q3GWTF Wedge Plate to my telescope?

    The Q3GWTF plate itself has female M42x0.75mm T-threads. You connect it to your telescope using an appropriate adapter, such as:

    • Daystar GM2DT: A 2" snout that threads into the plate, allowing you to slide the filter into a 2" focuser.
    • Daystar GF2SCTT: An adapter that threads into the plate and connects directly to the standard threads on the rear cell of an SCT.

    Is the Daystar Quantum Front Wedge Plate compatible with filters other than the Quantum series?

    No, this plate is specifically designed to be the front mounting plate for a Daystar Quantum series solar filter. It is not a standalone adapter and will not work with other filter types or brands.

    What is the difference between this wedged plate and a standard flat plate for a Quantum filter?

    A flat plate is used for on-axis applications where the filter is placed directly in the center of the telescope's light path. This wedged plate is required for off-axis applications to correct the optical angle, which is critical for proper filter function in that configuration.

    I want to use my Daystar Quantum filter with an 8" SCT and an off-axis energy rejection filter. Is the Q3GWTF the right part?

    Yes, this is the correct component for that exact scenario. The Daystar Quantum Front Wedge Plate is designed to mount your Quantum filter in an off-axis light path, such as the one created when using a sub-aperture energy rejection filter on the front of your 8" SCT.

    Can I use the Daystar Quantum Front Wedge Plate with a small 80mm refractor mounted on my SCT for solar viewing?

    Yes. If you are using a smaller refractor as a guidescope or secondary instrument for solar viewing, this plate allows you to attach your Quantum filter to it. You would use a T-thread adapter to connect the plate to the 80mm refractor's focuser, creating a dedicated, off-axis solar imaging system.
