Product Description:
This Variable Projection Camera Adapter , allows for a range of effective focal ratios during eyepiece-projection photography. Compatible with telescopes with 1.25" focuser. Inserts into any 1.25" eyepiece holder and a 1.25" eyepiece is then typically inserted into the adapter, usually in the 15mm to 32mm focal length range. The machined sliding-cell assembly can be fixed at any position along its length and is held in position via thumbscrew. The resulting effective focal ratio is then determined by the sliding adjustment and eyepiece used. For cameras, a T-Mount is required and can be ordered separately for your camera brand. Can be used for prime photography without eyepiece when using just the nosepiece.
The 1.25 inch Variable Universal Camera Adapters allow attachment of a camera body to reflector and refractor telescopes for either prime-focus or telescope eyepiece-projection photography.
