  • PrimaLuceLab 2" Visual Back for ESATTO 3"

    The PrimaLuceLab 2" Visual Back for ESATTO 3" is the essential adapter for using standard 2" eyepieces and accessories with your robotic focuser. This component threads directly onto the ESATTO 3" draw tube, converting it into a secure, non-marring 2" holder for visual observation or imaging with cameras that use a 2" nosepiece.

    Secure Connection for 2" Accessories via Brass Ring and Multi-Point Locking

    This visual back is engineered to protect your equipment while maintaining a rigid connection. A soft brass compression ring inside the barrel prevents the locking screws from directly touching and scratching the barrels of your eyepieces or camera nosepieces. The multiple locking screws are positioned around the collar to apply even pressure, ensuring your accessories are perfectly centered and held firmly without any tilt, even when supporting heavy cameras.

  • What is the PrimaLuceLab 2" Visual Back for ESATTO 3" used for?

    This adapter allows you to connect any standard 2" accessory, such as a diagonal, eyepiece, or a camera with a 2" nosepiece, to the PrimaLuceLab ESATTO 3" robotic focuser. It's the primary component needed for visual observation with the ESATTO 3".

    How does this visual back protect my 2" accessories from scratches?

    The PrimaLuceLab 2" Visual Back features an internal brass compression ring. When you tighten the locking screws, this soft metal ring gently clamps down on the accessory, preventing the hard steel screws from digging into and marring the barrel of your expensive eyepieces or camera nosepieces.

    How does the PrimaLuceLab 2" Visual Back attach to the ESATTO 3" focuser?

    The visual back threads directly onto the male threads of the ESATTO 3" focuser's draw tube for a secure, direct-fit connection with no flexure.

    Can I use the PrimaLuceLab 2" Visual Back with a heavy camera like a ZWO ASI2600MM Pro?

    Yes. The adapter is designed for a secure connection. Its multiple locking screws are arranged to provide a strong, centered grip, which is essential for preventing sag or tilt when using heavier imaging trains, including cameras like the ASI2600MM Pro that are fitted with a 2" nosepiece.

    Does this adapter add significant length to the ESATTO 3" imaging train?

    The PrimaLuceLab 2" Visual Back is designed to be as low-profile as possible to conserve precious back focus. While it adds a small amount of optical length, it is a very compact solution for adding a 2" eyepiece holder to your ESATTO 3" focuser.

    Is this the correct adapter for connecting a camera with M54 threads to my ESATTO 3"?

    No. This adapter is specifically for accessories that use a 2" slip-fit nosepiece. If your camera or accessory has female M54 threads, you will need a different adapter, such as the "PrimaLuceLab M81 to M54 Adapter with Stop Ring for ESATTO 3"".
