This adapter is specifically designed for QHYCCD color cameras with a native 17.5mm back focus, such as the QHY600C and QHY410C, creating a secure and standardized mounting point for M54 spacers and other telescope accessories.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eStandardize Your Imaging Train: The 6mm M54 Adapter\u003c\/h3\u003e\n\u003cp\u003eThe primary function of the CAA is to convert the camera's native dovetail connection into an M54 thread. This allows you to build a rigid and reliable imaging train using common M54-threaded components. The adapter consumes a fixed 6mm of back focus, a critical measurement to factor into your optical calculations to ensure you can reach focus with your specific reducer or flattener.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eSystem Integration: Compatibility with QHYCFW3L and Color Cameras\u003c\/h3\u003e\n\u003cp\u003eThis adapter is the same component QHYCCD includes with its QHYCFW3L 7-position filter wheel, listed as the \"CAA (Dovetail Ring to M54)\".
