  • PrimaLuceLab Adapter from M56 to M48 with Stop Ring for ESATTO 2"

    This PrimaLuceLab adapter seamlessly converts the M56 female thread on the ESATTO 2" focuser's draw tube to a standard M48x0.75 male thread, adding a minimal 4mm of optical length to your imaging train. It provides a secure, direct-threaded connection for any M48-compatible camera, off-axis guider, or filter wheel. The integrated stop ring allows you to lock your camera's orientation, ensuring perfect sensor alignment and framing for every target.

    A Minimal 4mm Optical Path for M48 Accessories

    Engineered for imagers conscious of back focus, this adapter consumes only 4mm of optical path. The adapter body itself is just 1.5mm thick, while the included stop ring accounts for the other 2.5mm. This allows you to integrate M48 accessories into your ESATTO 2" setup without consuming significant back focus, preserving compatibility with reducers and other correctors.

    Precise Framing with the ESATTO 2" M48 Stop Ring

    The included M48 stop ring is the key to achieving perfect rotational alignment. After threading your camera onto the adapter, you can rotate it to the desired angle and then lock it in place by tightening the stop ring against the camera body. This prevents the camera from rotating during an imaging session and allows you to precisely frame objects like the Andromeda Galaxy (M31) or the Horsehead Nebula (B33) without adjusting the entire optical tube.

  • What is the primary function of the PrimaLuceLab M56 to M48 Adapter?

    This adapter allows you to connect astrophotography cameras, filter wheels, or other accessories that use a standard M48x0.75 female thread to the draw tube of a PrimaLuceLab ESATTO 2" robotic focuser, which has an M56 thread.

    How does the M48 stop ring on the ESATTO 2" adapter work?

    The stop ring is a separate, threaded ring that allows for precise rotational framing. You first thread the stop ring onto the adapter, then your camera. You can then loosen the stop ring, rotate your camera to the perfect angle, and then tighten the ring up against the camera body to lock its position securely.

    How much back focus does the PrimaLuceLab M56 to M48 adapter use?

    The adapter adds a total of 4mm to your optical path. This is composed of the 1.5mm thick adapter itself and the 2.5mm thick stop ring.

    Can I use this adapter to attach my M48-threaded ZWO or QHY camera to an ESATTO 2" focuser?

    Yes, absolutely. This is the correct adapter for connecting any camera with a standard M48x0.75 female thread directly to the ESATTO 2" focuser for a secure, rigid imaging train.

    Is this the right adapter for using a 2" eyepiece or diagonal with the ESATTO 2"?

    No. This adapter is specifically for M48 threaded accessories. For visual observation with 2" eyepieces or a diagonal, you need the dedicated "2" Visual Back for ESATTO 2"," which provides a compression ring eyepiece holder.

    How do I install the M56 to M48 Adapter on my ESATTO 2"?

    Installation is straightforward. Simply thread the M56 female side of the adapter directly onto the M56 male thread on the end of the ESATTO 2" focuser's draw tube until it is snug. Then, you can attach your M48 accessories to the other side.
