  • PrimaLuceLab 2" Visual Back for ESATTO 2"

    The PrimaLuceLab 2" Visual Back provides the essential M56 threaded connection for using standard 2-inch accessories with your ESATTO 2" robotic focuser or ARCO 2" rotator. This adapter allows you to securely attach 2" diagonals for visual observing or camera nosepieces for imaging. It features a non-marring brass compression ring and three locking screws to firmly hold heavy equipment without damaging your accessory barrels.

    Secure, Non-Marring Connection for 2" Accessories

    This visual back is engineered to protect your investment in eyepieces and cameras. An internal brass compression ring distributes clamping force evenly around the barrel of your accessory, preventing the gouges and scratches commonly caused by single-screw designs. Three locking screws, spaced 120° apart, provide a perfectly centered and exceptionally strong grip, ensuring your imaging train remains rigid and free of tilt, even when loaded with heavy cameras or binoviewers.

    M56 Thread for Native ESATTO 2" and ARCO 2" Integration

    Designed as a native component of the PrimaLuceLab ecosystem, this visual back features an M56 female thread that attaches directly to the draw tube of the ESATTO 2" microfocuser. This direct-thread connection eliminates potential flexure from stacked adapters. It is also the correct adapter for adding a 2" eyepiece holder to the ARCO 2" rotator, enabling you to manually frame targets with your camera before engaging the rotator.

  • What is the PrimaLuceLab 2" Visual Back for ESATTO 2" used for?

    This adapter allows you to connect standard 2-inch accessories, such as diagonals, eyepieces, or camera nosepieces, to the M56 thread on the draw tube of a PrimaLuceLab ESATTO 2" robotic focuser or ARCO 2" rotator.

    How do I use the PrimaLuceLab 2" Visual Back to observe Jupiter with my ESATTO 2" focuser?

    To observe a planet like Jupiter, you simply thread the visual back directly onto the M56 draw tube of your ESATTO 2". Then, insert your 2" diagonal into the visual back, secure it with the three locking screws, and add your preferred 2" eyepiece to the diagonal. You can then use the ESATTO to achieve perfect focus.

    Will this PrimaLuceLab visual back scratch my eyepieces?

    No, it is designed to prevent damage. The adapter features an internal brass compression ring that tightens uniformly around the accessory barrel. This avoids the direct metal-on-metal contact of a simple thumbscrew, which can scratch and mar your equipment.

    Can the PrimaLuceLab 2" Visual Back hold a heavy camera for astrophotography?

    Yes. The combination of the secure M56 thread connection and the three locking screws provides a very rigid and stable hold. This system is designed to support the weight of typical imaging setups, including DSLRs or dedicated astronomy cameras with filter wheels, without introducing tilt or flexure.

    Is this adapter compatible with the PrimaLuceLab ARCO 2" rotator?

    Yes. This 2" visual back threads into the M56 port on the ARCO 2" rotator, allowing you to use 2" accessories with it. This is useful for attaching a camera with a 2" nosepiece or for visual use through the rotator.

    I need to place my camera further from the ESATTO 2". Is this the right part?

    No, this visual back adds minimal optical length. If you need to increase the distance between your focuser and camera to achieve focus, you should use an M56 extension tube, which is designed specifically for that purpose within the PrimaLuceLab system.
