ZWO M42-M48 Extender (16.5mm)

The ZWO M42-M48 Extender is a precision-machined adapter designed to provide a secure and rigid connection in your astrophotography imaging train. With a male M42x0.75 thread on one side and a male M48x0.75 thread on the other, this extender is perfect for bridging the gap between cameras, filter wheels, and optical correctors that have different thread sizes. The 16.5 mm length is a crucial measurement often required to achieve the precise back focus distance for many field flatteners, reducers, and correctors, ensuring your images are free of vignetting and have pinpoint stars across the entire frame. Crafted from durable aluminum, this extender adds no unwanted flex to your setup.
