The digital photo adapter allows for precise positioning of the camera. Once mounted, you can slide the camera aside and continue your observation through the ocular. If you wish to take a picture, slide the adapter with the mounted camera to the ocular lens until the pivot arm clicks closed. Now you can take pictures. It is well-suited for ocular lenses with a larger exit pupil, providing vignetting-free full-frame images, such as those of the moon's surface. This 2" camera adapter is designed for digital compact cameras with a non-removable lens and is compatible with spotting scopes, binoculars, and astro telescopes with an ocular diameter of 30 to 63 mm. The sturdy pivot arm features a snap-in locking device for cameras weighing up to 1 kg.
