Connects Baader UFC Base to a Camera Camera-Side Thread: Male M48 x 0.75 Provides a Wide, Non-Vignetting Aperture Designed for the Modular UFC System Description FAQ Specifications In the Box Downloads Warranty Baader UFC Camera Side Adapter - M48(M) The Baader UFC Camera Side Adapter provides a secure, direct connection from the UFC Base to any camera or accessory with a female M48 thread. It presents a male M48 thread to the camera side, creating a rigid attachment point for your imaging train. Secure M48 Camera Integration with the UFC Base This adapter is a core component of Baader's Universal Filter Changer (UFC) system, allowing you to integrate your filter setup with cameras that use the common M48 thread standard. The adapter attaches firmly to the UFC Base via an included mounting plate, ensuring a flexure-free connection essential for astrophotography. The M48 interface provides a larger clear aperture than older T-2 threads, making it the ideal choice for cameras with APS-C or larger sensors. This wider light path helps to prevent vignetting, ensuring your flat frames can correct for illumination fall-off from the optics, not the adapters. UFC M48 vs. T-2 (M42) Adapters: Choosing Your Connection While the T-2 (M42) thread is a long-standing standard, the M48 thread on this adapter offers a distinct advantage for modern imaging. The choice depends entirely on your camera's sensor size and input threads. T-2 (M42) Adapter: Better suited for cameras with smaller sensors, such as planetary cameras or guide cameras, where the smaller physical aperture does not restrict the light cone. M48 Adapter (This Model): Essential for cameras with APS-C, full-frame, or larger sensors. The wider M48 aperture is necessary to illuminate the entire sensor without introducing artificial vignetting from the adapter itself. What is the main purpose of the Baader UFC M48 Adapter? The Baader UFC M48 Adapter connects the main Baader UFC Base (the part that holds the filter sliders) to an astronomy camera or accessory that has female M48 x 0.75 threads. It creates a secure, wide-aperture link in your imaging train. How do I attach the Baader UFC M48 Adapter to the UFC Base? The adapter attaches to the camera-facing side of the UFC Base unit. It uses an included mounting plate and screws to ensure a solid, non-rotating connection between the filter chamber and the rest of your imaging train. Should I choose the Baader UFC M48 Adapter or the T-2 version for my ZWO ASI2600MC Pro camera? You should choose this Baader UFC M48 Adapter. The ZWO ASI2600MC Pro has an APS-C sensor and native M48 threads. Using a smaller T-2 adapter would constrict the light path and cause significant vignetting on a sensor of that size. Will the Baader UFC M48 Adapter cause vignetting with my full-frame camera? The M48 thread is specifically designed to minimize vignetting on sensors up to full-frame (36mm x 24mm). While some light fall-off is inherent in any optical system, this adapter provides the largest possible clear aperture in the UFC system for this thread type, making it the correct choice for full-frame imaging. Is the Baader UFC M48 Adapter compatible with accessories other than cameras? Yes. Any accessory that terminates in a female M48 thread can be connected. This could include certain off-axis guiders, rotational adapters, or extension tubes that you wish to place after your filter wheel. What components do I need besides the Baader UFC M48 Adapter to use filters? This adapter is only one part of the modular system.
