One end features standard male M42 x 0.75 threads (the universal \"T-thread\") for a secure connection to your DSLR's T-ring or a dedicated astronomy camera. The other end is a 1.25\" barrel that slides into any standard telescope focuser or diagonal, just like an eyepiece.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n  \n  \u003cdiv class=\"DAV-bg-light\"\u003e\n    \u003cdiv class=\"DAV-section\"\u003e\n      \u003ch3\u003eSecure Prime-Focus Imaging with a 1.25\" Barrel\u003c\/h3\u003e\n      \u003cp\u003eBy creating a rigid, threaded connection, the adapter ensures your camera remains perfectly aligned with the telescope's optical axis. This prevents tilt, which can ruin stars in the corners of your frame, and maintains a consistent focal plane for sharp images.
