  • William Optics Pair of Riser Blocks

    This William Optics Pair of Riser Blocks is the straightforward solution for common telescope mounting problems. Specifically designed for the William Optics Universal system, these blocks create essential space between your optical tube and the saddle plate. This added height prevents larger cameras, filter wheels, or electronic focusers from colliding with the mount during slewing or meridian flips, safeguarding your equipment and ensuring uninterrupted imaging sessions.

    Essential Clearance for William Optics Universal Systems

    When assembling a modern astrophotography rig, clearance is a critical factor. The William Optics Riser Blocks are engineered to elevate your telescope, providing the room needed to accommodate today's larger accessories. This elevation is key to achieving a greater range of motion, particularly near the meridian, where the risk of collision between your imaging train and the mount is highest.

    Beyond preventing physical impacts, these blocks also offer greater flexibility in balancing your setup. By raising the telescope, you create more latitude to slide the entire assembly forward or backward, making it easier to achieve perfect balance, especially with heavy or off-center payloads. This results in more accurate tracking, sharper stars, and less strain on your mount's drive motors.

  • What is the primary purpose of the William Optics Riser Blocks?

    The primary purpose of the William Optics Riser Blocks is to increase the distance between the telescope tube and the mount saddle. This provides critical clearance for large accessories like cameras and filter wheels, preventing them from hitting the mount, and offers more flexibility for achieving precise balance.

    Which mounting systems are these Riser Blocks designed for?

    These riser blocks are specifically designed to be compatible with William Optics Universal mounting systems. They are intended to integrate seamlessly with this hardware platform.

    Will these William Optics Riser Blocks help if my camera hits my mount?

    Yes. This is one of the main problems they solve. By elevating your telescope, the riser blocks create extra space that can prevent your camera body, filter wheel, or cables from colliding with the mount deck or tripod legs, especially when imaging objects near the celestial meridian.

    How do the William Optics Riser Blocks improve telescope balance?

    Achieving perfect balance is crucial for autoguiding and tracking. The riser blocks provide more physical room to slide your telescope's dovetail plate within the saddle. This makes it easier to counteract the weight of a heavy imaging train at the rear or a large dew shield at the front, ensuring the entire system's center of gravity is correctly positioned over the mount's axes.

    What kind of hardware is needed to attach the William Optics Riser Blocks?

    The blocks are designed to be installed between your telescope's tube rings or mounting plate and the dovetail bar. You will typically need longer versions of the screws you would normally use to attach your dovetail. The exact length and thread type will depend on your specific rings and dovetail bar, so you should measure to ensure a secure fit.

    Can I use these William Optics blocks to mount a guide scope?

    These blocks are designed to raise the entire primary telescope assembly. They are not intended for mounting a guide scope directly. To mount a guide scope, you should use a dedicated guide scope ring system attached to the top of your main telescope's tube rings or a top-mounted dovetail bar.
