  • Adapter from M60 to M54 with stop ring for ESATTO 2” LP

    The Adapter for ESATTO 2” LP converts the focuser's native M60 thread to a standard M54 connection for cameras and accessories. It maintains a minimal light path, adding only 2.5mm of optical thickness with its stop ring installed, or zero thickness when the ring is removed for systems with critical backfocus requirements.

    M60 to M54 Conversion with a 2.5mm Profile

    This adapter creates the essential M60 male to M54 female threaded connection needed to attach modern imaging trains to the ESATTO 2" LP focuser. With the stop ring in place, the adapter contributes a minimal 2.5mm to the optical path, preserving precious backfocus. For setups where every millimeter is critical, removing the stop ring reduces the added optical thickness to zero.

    Precise M54 Camera Framing with the Integrated Stop Ring

    The key feature of this adapter is the integrated M54 stop ring. This mechanism allows you to thread your camera or accessory on, then lock its rotational position precisely. This is critical for optimally framing targets like the Horsehead Nebula (Barnard 33) or aligning your sensor with the axes of your mount.

  • What is the main purpose of the M60 to M54 adapter for the ESATTO 2” LP?

    Its primary function is to allow you to connect cameras, off-axis guiders, filter wheels, or any other accessory with a standard M54x0.75 female thread to the M60 draw tube of the PrimaLuceLab ESATTO 2” LP focuser.

    How does the stop ring on the M60 to M54 adapter help when imaging a target like the Andromeda Galaxy (M31)?

    The stop ring lets you rotate your camera to the perfect angle to fit a large object like the Andromeda Galaxy (M31) within your sensor's frame. Once you find the ideal orientation, you can lock it in place, ensuring your composition doesn't shift during an imaging session.

    What is the optical thickness of the ESATTO 2” LP M60 to M54 adapter?

    The adapter has two optical thickness configurations depending on your needs:

    • With Stop Ring: Adds 2.5mm to the optical path.
    • Without Stop Ring: Adds zero thickness, which is ideal for imaging setups with very limited backfocus.

    Can I use this ESATTO 2" LP adapter with a different brand of focuser?

    This adapter is specifically designed for the M60 male thread on the ESATTO 2” LP draw tube. While it might physically thread into other focusers with an M60 thread, its optical thickness and stop ring function are optimized for the PrimaLuceLab ecosystem and correct fit is not guaranteed.

    If I connect my camera to a Celestron RASA using the ESATTO 2” LP, why is the 'zero thickness' option important?

    Fast optical systems like a RASA have extremely critical backfocus tolerances. By removing the stop ring, the adapter's optical thickness becomes zero, consuming none of your available backfocus. This helps ensure you can place your camera sensor at the telescope's precise focal plane for sharp stars across the entire field.

    Does removing the stop ring affect my ability to connect M54 accessories to the ESATTO 2" LP?

    No, you can still securely thread any M54 accessory directly to the adapter. You will simply lose the ability to lock the rotation at a specific angle. The primary M60-to-M54 conversion function remains the same.
