  • PrimaLuceLab M48 Male to T2 Female Adapter

    The PrimaLuceLab M48 Male to T2 Female Adapter solves the common M48 (48x0.75mm) to T2 (42x0.75mm) thread mismatch while adding only 3mm of optical path length, preserving critical back-focus for flatteners, reducers, and cameras.

    A 3mm Low-Profile M48 to T2 Conversion

    This adapter converts any female M48 thread into a female T2 thread, allowing you to connect T2-male accessories directly. Its key design feature is an exceptionally thin profile that consumes just 3mm of back-focus, making it an essential component for complex imaging trains where every millimeter counts.

    Integrating M48 Accessories with T2 Imaging Trains

    Many imaging accessories, like filter wheels or off-axis guiders, terminate in a female M48 thread to maximize aperture and prevent vignetting. This adapter lets you securely step down that connection to the T2 standard used by many astronomy cameras and correctors, ensuring broad compatibility without introducing flexure.

    • Solid Construction: Machined entirely from metal and black anodized to eliminate internal reflections that could reduce contrast.
    • Precise Function: Allows you to securely attach accessories with a male T2 thread into components that have a female M48 thread.

  • What is the primary function of the PrimaLuceLab M48 to T2 adapter?

    Its primary function is to connect an accessory with a male T2 (42x0.75mm) thread to a component with a female M48 (48x0.75mm) thread. In effect, it converts a female M48 port into a female T2 port.

    How much back-focus does the PrimaLuceLab M48 to T2 adapter consume?

    The adapter is designed to be very thin and adds only 3mm of thickness to the optical path. This minimal profile helps preserve precious back-focus in your imaging train.

    I have a filter wheel with an M48 female thread and a camera with a T2 male thread. Is this the right adapter?

    Yes, this is the correct adapter for that scenario. You would screw the M48 male side of this adapter into your filter wheel, which then presents a female T2 thread for your camera's male T2 nosepiece to connect to.

    Can I use the PrimaLuceLab M48 to T2 adapter to connect an M48 field flattener to my T2-threaded camera?

    Yes. If your field flattener has a female M48 thread on the camera side, you can insert this adapter to convert it to a female T2 thread, allowing direct connection to a camera with a male T2 interface.

    What is the PrimaLuceLab M48 to T2 adapter made of?

    The adapter is made entirely of metal with a black anodized finish. This ensures a rigid, non-reflective connection between your components.

    Does this adapter convert a male M48 thread into a male T2 thread?

    No, this adapter is M48 male to T2 female. It is designed to be screwed into a female M48 thread, thereby creating a female T2 thread. It does not adapt male-to-male or female-to-female connections directly.
