- Standard T-Thread (M42x0.75) Camera Interface
- Matte Black Interior Minimizes Internal Reflections
- Durable All-Metal Construction
The iOptron iAFS2 2'' Camera Adapter provides the essential, rock-solid link between your camera and any telescope equipped with a 2-inch focuser. This adapter is engineered to create a secure, threaded connection, eliminating the flexure and potential tilt that can occur when using simpler set-screw holders. By ensuring your camera's sensor is held perfectly parallel to the focal plane, the iAFS2 is a fundamental component for achieving sharp, high-contrast astrophotos.
The primary function of the iAFS2 adapter is to replace the standard 2" eyepiece holder with a fully threaded, rigid connection point. The nosepiece slides into your telescope's focuser or visual back, while the threaded interface provides a secure attachment for your imaging train. This method is critical for astrophotography, as it prevents the camera from sagging or shifting during a long exposure, which would otherwise result in trailed or misshapen stars.
Designed for maximum compatibility, the iAFS2 features standard male T-threads (M42x0.75) on the camera side. This allows it to connect directly to the T-ring of virtually any DSLR or mirrorless camera, as well as to the front of most dedicated astronomy cameras and filter wheels. The interior of the adapter is machined with a matte black, non-reflective finish to absorb stray light and ensure your images have the darkest possible background.
The iOptron iAFS2 2'' Camera Adapter is designed to create a secure, rigid connection between a camera and a telescope's 2-inch focuser. It prevents camera tilt and flexure, which is essential for sharp, long-exposure astrophotography.
This adapter is compatible with any telescope that has a 2-inch focuser, visual back, or diagonal. This includes most Schmidt-Cassegrains, refractors, and Newtonian reflectors designed for astrophotography.
You will need a T-ring that is specific to your camera's lens mount (e.g., a Canon EOS T-ring or a Nikon F-mount T-ring). The T-ring attaches to your camera body in place of a lens, and the iAFS2 adapter then threads onto the T-ring.
By providing a solid, threaded connection, the iAFS2 adapter ensures your camera sensor remains perfectly aligned with the telescope's optics. It also features a blackened interior to absorb stray light. These two features lead to:
The nosepiece of the iAFS2 adapter is typically threaded to accept standard 2-inch (M48) astronomy filters. This allows you to place a light pollution, nebula, or color filter directly in the light path before it reaches the camera sensor.
The iAFS2 is built with durable metal construction to provide a secure connection. While it offers a much more rigid solution than a simple set-screw holder, you should always ensure your telescope's focuser itself can handle the total weight of your imaging train (camera, filter wheel, off-axis guider, etc.) without slipping or flexing.
